Pull request overview
This PR integrates LI.FI Intents into the Earn deposit/withdraw and concierge flows, adding order construction, status polling, escrow lifecycle UI, and cross-chain Composer fallback handling.
Changes:
- Adds LI.FI Intents proxy/client utilities, escrow order helpers, nonce/deadline encoding, and status timeline components.
- Extends deposit/withdraw flows with Intent routes, Composer cross-chain bridge+deposit execution, and richer execution event tracking.
- Updates token typing/copy to tolerate missing symbols and clarify risk/fallback messaging.

wagmiWaitForReceipt does not fail just because a tx reverted, so this helper currently treats reverted approve transactions as success and continues the flow. In that case the next step (open, sendTransaction, etc.) runs with unchanged allowance and fails later with a misleading error path. Please inspect the returned receipt status (for both reset and final approve txs) and throw when it is reverted.

This subtraction can throw when postBridgeDestBalance < preBridgeDestBalance (for example if the user transfers tokens out while the bridge is settling, or balance shifts for other reasons). Because ethers.BigNumber.sub underflow throws, the code bypasses the intended recoverable delta <= 0 branch and fails the flow unexpectedly. Compare first and clamp to zero before subtracting so the recoverable path is preserved.
