feat(pwa): installable PWA + responsive mobile dashboard

- Add Web App Manifest + ArbPulse icons (192/512/maskable/apple-touch) under
  web/public/; no service worker (real-time honesty: never serve stale data).
- Add mobile/install metadata to index.html (theme-color, viewport-fit=cover,
  apple-mobile-web-app-*, manifest + apple-touch-icon links).
- Responsive layout: PriceMatrix stacked per-venue cards below sm, StatsBar
  reflow, ~44px touch targets in Controls/ConfigPanel, safe-area top inset.
- scripts/gen-icons.ps1 derives icon sizes from the master (no new deps).
- openspec: add-pwa-mobile change (proposal/design/specs/tasks).

## Context
The dashboard (`web/`, React 18 + Vite 6 + Tailwind v3) is served by Express as
static files from `web/dist` (same origin as `/api` + SSE). `App.tsx` already uses a
`grid-cols-1 lg:grid-cols-3` layout, so it collapses to a single column on mobile,
but two things are missing for a good phone experience: (1) the `PriceMatrix` order
book is a 6-column `<table>` that overflows horizontally on ~360430px screens, and
(2) there is no install/mobile metadata (manifest, theme-color, apple-touch-icon).
The app is real-time: the frontend consumes `/api/state` over SSE and shows a
`connected` badge. A domain rule (honesty) forbids ever presenting stale or fake
market data. The target runtime is the 24/7 VPS behind HTTPS at
`arbpulse.wayool.com` (nginx + certbot, Cloudflare DNS-only).
## Goals / Non-Goals
**Goals:**
- Installable to the phone home screen (standalone, branded icon).
- Responsive, touch-friendly dashboard on phones without regressing desktop.
- Zero risk of showing cached/stale market data.
- No new runtime dependencies; no change to build/deploy steps.
**Non-Goals:**
- Offline support of any kind (no cached app shell, no cached data).
- Push notifications / background sync.
- A native app or app-store packaging.
- Redesigning the dashboard; this is layout + metadata only.
## Decisions
### D1: No service worker (installable via manifest + HTTPS only)
Since Chrome 108 (mobile) / 112 (desktop), a service worker is no longer required to
install from the browser menu / "Add to Home Screen"; iOS Safari never required one.
No-op `fetch` handlers are now actively skipped and warned about by Chrome. Because
this app must never serve cached data, we ship **no service worker at all**.
- **Chosen:** manifest + icons + HTTPS → installable; SSE always fetches live data.
- **Alternatives:** `vite-plugin-pwa`/Workbox with a shell precache (rejected: its
value is offline/precaching, which conflicts with the no-stale-data rule and adds
a dependency); a minimal passthrough SW just to get the auto-install banner
(rejected: Chrome ignores no-op fetch handlers, and it adds a moving part for a
banner we don't need — manual install from the menu is sufficient).
- **Trade-off:** no automatic install prompt on Android; users install from the
browser menu (the only path on iOS anyway). Acceptable.
### D2: PriceMatrix responsive strategy — stacked cards below `sm`
Render per-venue cards (exchange + bid/ask/qty/spread as labelvalue rows) on small
screens and keep the existing `<table>` from `sm` up.
- **Chosen:** Tailwind responsive classes to swap layouts (`block sm:table` pattern
or two branches gated by breakpoint) — no JS, no `matchMedia`, purely CSS.
- **Alternative:** wrap the table in `overflow-x-auto` (rejected as primary: a
6-column price table sideways-scrolling on a phone is poor UX for the primary
widget; horizontal scroll can remain as a defensive fallback).
### D3: Icons derived from one master
Generate a single ArbPulse master icon (pulse line → Bitcoin "B", blue→green on
`#0a0e14`) and derive `icon-192.png`, `icon-512.png`, `icon-maskable-512.png`
(with safe padding), and `apple-touch-icon.png` (180). Store under `web/public/` so
Vite copies them verbatim to `web/dist`.
- **theme_color/background_color:** `#0a0e14` (matches the dashboard background).
### D4: Manifest + head metadata, same-origin
`manifest.webmanifest` uses `start_url: "/"`, `scope: "/"`, `display: "standalone"`.
`index.html` adds `theme-color`, `apple-mobile-web-app-capable`,
`apple-mobile-web-app-status-bar-style`, `apple-mobile-web-app-title`,
`viewport-fit=cover` (already has `width=device-width, initial-scale=1`), and links
to the manifest + apple-touch-icon. Everything is same-origin, so no CORS/proxy
concerns and the existing Express static + SPA fallback serve it unchanged.
## Risks / Trade-offs
- [Stale data if a SW is ever added later] → Documented no-SW decision; if a SW is
introduced in the future it MUST deny-list `/api` and never cache the SSE stream.
- [iOS quirks: no auto-prompt, status-bar/notch rendering] → Provide
`apple-touch-icon`, `apple-mobile-web-app-*`, and `viewport-fit=cover`; verify on a
real iPhone (Add to Home Screen), not just Android.
- [PriceMatrix layout duplication risk] → Keep a single data mapping and switch only
presentation via breakpoints to avoid divergent desktop/mobile logic.
- [Maskable icon getting cropped] → Keep the glyph within the ~80% safe zone in the
maskable variant.

## Why
The Arb Pulse dashboard is desktop-first: the 3-column grid collapses acceptably on
narrow screens, but the order-book table overflows horizontally and there is no
mobile/PWA metadata. We want to demo and monitor the engine from a phone —
installable to the home screen, full-window, and touch-friendly — while the app
runs 24/7 on the VPS behind HTTPS (`arbpulse.wayool.com`).
## What Changes
- Make the dashboard fully responsive on phones (~360430px): stack the
`PriceMatrix` order book as per-venue cards below `sm`, reflow the `StatsBar`
badges, and ensure touch targets are at least ~44px in `Controls`/`ConfigPanel`.
- Add a Web App Manifest (`web/public/manifest.webmanifest`) so the dashboard is
installable to the home screen (name/short_name, `start_url`, `display: standalone`,
theme/background color, icons).
- Add ArbPulse app icons (192, 512, a maskable variant, and a 180px
`apple-touch-icon`) under `web/public/`.
- Add mobile/install metadata to `web/index.html`: `theme-color`,
`apple-mobile-web-app-*`, `viewport-fit=cover`, and links to the manifest and
apple-touch-icon.
- **No service worker and no offline support.** The app is real-time (SSE); it must
never serve cached/stale market data. Installability comes from the manifest +
HTTPS (menu / "Add to Home Screen"), not from a cached shell. When disconnected
the UI shows its existing "reconnecting/offline" state, never fake data.
## Capabilities
### New Capabilities
- `pwa`: installability and mobile-web behavior of the dashboard — how the app is
installable to the home screen via manifest + HTTPS with no service worker, how
it stays responsive on small screens, and the explicit no-offline / no-stale-data
guarantee for this real-time app.
### Modified Capabilities
<!-- None: responsiveness and install metadata are new behavior; no existing spec's requirements change. -->
## Impact
- Frontend: `web/index.html` (head metadata), `web/public/` (new manifest + icons),
`web/src/components/PriceMatrix.tsx` and `StatsBar.tsx` (responsive layout),
minor touch-target tweaks in `Controls.tsx`/`ConfigPanel.tsx`.
- Build/serve: none — `npm run build` copies `web/public/` into `web/dist`, already
served by Express static; the Docker image bakes it in. No new deploy steps.
- Dependencies: none added (no `vite-plugin-pwa`/Workbox, since there is no SW).
- Behavior: no API, wire-format, or engine changes. Desktop layout unchanged.
- Testing: verified on a real phone at `https://arbpulse.wayool.com` after the
normal `dev → PR → main → deploy.sh` flow.

## ADDED Requirements
### Requirement: Installable to the home screen
The dashboard SHALL be installable to a device home screen via a Web App Manifest
served over HTTPS, without requiring a service worker.
#### Scenario: Manifest is present and valid
- **WHEN** the dashboard is loaded over HTTPS
- **THEN** a linked `manifest.webmanifest` is served that includes `name`,
`short_name`, `start_url` in scope, `display: standalone`, `theme_color`,
`background_color`, and at least 192px and 512px PNG icons
#### Scenario: User installs from the browser
- **WHEN** a user chooses "Install app" / "Add to Home Screen" from the browser menu
- **THEN** the app is added with the ArbPulse icon and launches in a standalone,
full-window mode at `start_url`
### Requirement: No offline mode and no stale data
The app SHALL NOT register a service worker and SHALL NOT cache market data, so it
never presents stale or fake data (real-time honesty rule).
#### Scenario: No service worker is registered
- **WHEN** the dashboard runs in any environment
- **THEN** no service worker is registered and no application cache stores `/api`
responses or the SSE stream
#### Scenario: Disconnected device shows a clear non-data state
- **WHEN** the device has no working connection to the engine
- **THEN** the UI shows its reconnecting/offline indicator and does not display
cached market figures as if they were live
### Requirement: Responsive mobile layout
The dashboard SHALL be usable on phone-sized viewports (~360430px wide) without
horizontal overflow of primary widgets, while the desktop layout is unchanged.
#### Scenario: Order book fits a phone screen
- **WHEN** the viewport is narrower than the `sm` breakpoint
- **THEN** the order-book (`PriceMatrix`) is presented as per-venue stacked cards
showing bid, ask, quantities, and spread without horizontal scrolling
#### Scenario: Stats and controls remain readable and tappable
- **WHEN** the dashboard is viewed on a phone
- **THEN** the stats bar reflows without clipping and interactive controls have
touch targets of at least ~44px
#### Scenario: Desktop layout is preserved
- **WHEN** the viewport is at the `lg` breakpoint or wider
- **THEN** the existing multi-column layout and table order book render as before
### Requirement: Mobile and install metadata
The `index.html` head SHALL include the metadata needed for correct mobile rendering
and home-screen installation on Android and iOS.
#### Scenario: Head includes mobile/install tags
- **WHEN** the page is served
- **THEN** the head contains a `theme-color`, `viewport-fit=cover` in the viewport
meta, a link to the manifest, an `apple-touch-icon`, and the
`apple-mobile-web-app-*` tags for standalone iOS launch
