feat: SHEEP CHOICE routing, cross-chain deposits, and any-token ZAP

One commit because the pieces do not compile apart: the shared copy, the tab
shell and the data layer all changed together, and splitting them further would
mean inventing intermediate states that never existed.

SHEEP CHOICE — the terminal's own swap. Quotes come from a solver that splits
one trade across several pools instead of forcing it down a single path, and
returns a ready-to-sign Settler transaction; the UI draws the split leg by leg
and scores every venue against one shared fee-free baseline, so the card that
says it pays most actually does. The Kyber transaction path is gone — Kyber is
read-only USD valuation now, and there is no Kyber calldata to sign.

BRIDGE — deposits from other chains over Relay, Across and the native portal,
priced side by side and sorted by what actually reaches you. No fee on any of
them. In-flight transfers get a countdown and survive a reload.

ZAP — add liquidity holding neither side of the pair; whatever needs swapping
is done in the same flow, with an optional stake-after step. Uniswap V2
liquidity now shows up under POSITIONS.

Swaps in flight are persisted, so a refresh mid-swap no longer loses the
transaction. Pair labels copy their token and pool addresses, and jump to
DexScreener.
