Summary

Fix false “Could not read token allowance — the token contract may not exist on this chain” on EVM deposits (reproduced with BSC vFDUSD → Terra while balance rendered correctly).
Read allowance(owner, bridge) through getEvmClient(sourceChainConfig) (same source RPC as balance / code preflight), instead of wallet-bound wagmi useReadContract.
Document INV-FE-EVM-ALLOWANCE-1 and cross-link in skills/agent-frontend-bridge-chains.md.

Related to #133 (vFDUSD bridge UI follow-up).

Test plan

Pre-commit: frontend typecheck + lint
npm run test:run -- src/hooks/useBridgeDeposit.test.ts
After deploy: BSC → Terra Classic with vFDUSD (~2.44) from 0xCd4E…F39c to terra1xsec…ydp8l — should proceed to approve/deposit instead of allowance error
Confirm approve spender is Bridge 0xb2A22c74…5369 and deposit succeeds
