fix(confirm): address review findings on the trade confirmation gate

- Escape every non-visible character in the confirmation block by Unicode
  property (\p{C}, \p{Z}, \p{M}, Default_Ignorable_Code_Point, U+2800) instead
  of a hand-kept list; soft hyphens, Hangul fillers, tag characters etc. can no
  longer make a fee-share username look like another.
- Fold only fields a command declares as blobs (cooking --image); key fields
  are always shown in full. multi-swap and strategy create/cancel now validate
  their addresses like swap does.
- Judge protections on the values being sent (min_output 0, anti_mev_mode off,
  expire_in 0 now warn), and reject NaN / Infinity / negative --slippage,
  --percent, --expire-in, --dev-wallet-bps before they reach a signed body.
  --gas-price is converted gwei→wei exactly (was float-rounded).
- Total tip / priority fees per container, including sell_param / buy_param and
  buy_trade_config / sell_trade_config, so section ① no longer understates.
- Anti-MEV warning only where accurate: none for swap (documented default on),
  "server default applies" for multi-swap / strategy on sol / bsc / eth, and
  an explicit "off" warning for cooking create on sol.
- Bind confirmations to method + route + query + body, and require one for
  every signed non-GET request (deny by default) instead of a path allowlist.
- In interactive mode write the block to /dev/tty, so the process launcher
  cannot filter what the human reads before typing yes.
- Display: swap --percent shows the bps line first and marks input_amount as
  ignored; strategy amount_in_percent and multi-swap per-wallet bps show "% of
  balance"; multi-swap shows the wallet count.
- Group risky leaves in linear time; load credentials before confirmation so a
  missing key is reported before the user types yes.
- Sync skills/gmgn-swap, skills/gmgn-cooking and docs/cli-usage.md with the
  gated order strategy cancel and its --yes flag.

For non-interactive/automated use you must both set `GMGN_ALLOW_AUTOMATED_TRADES=1` in your shell and pass `--yes`; `--yes` alone is rejected.
