The Bridge screen let a user type any amount and enabled the Swap
button regardless of what they actually held, unlike the Swap screen
which shows a live "Max: X" and disables on overflow. The confirm-step
ValidationSystem would still catch it before signing, but only after
routing through Send - no immediate feedback on the Bridge screen
itself.
Wires WalletInteractor.assetFlow(chainId, assetId) to the currently
selected origin side (re-subscribed on every direction/pair change),
tracking Asset.transferable - the same field the real transfer
validation checks. Reuses the existing MaxAmountView/MaxAvailableView
widget the Swap screen already uses for the "Max: X" display, and adds
a matching error-bordered state to BridgeAssetInputView. The
"Insufficient balance" string (bridge_insufficient_balance) was
already translated into every locale but never wired to any code.
Replaces the segmented pair/direction buttons and plain-text amount
sections with token-icon cards (BridgeAssetInputView), a one-tap flip
button, and a bottom-sheet pair picker (BridgePairListBottomSheet).
BridgeViewModel gains only additive presentation data (fromCard/toCard/
pairOptions, derived from the existing pair/direction state and the
same chainId/assetId mapping swapClicked() already used) - all bridge
business logic (rate, fee, minimum, liquidity warnings, submission)
is unchanged.
