This PR introduces significant changes to the bridge/swap functionality with new CowSwap intent transaction support:

1. Critical Engine Changes: The transaction-controller-messenger.ts adds new allowedActions including BridgeStatusController:submitTx, KeyringController:signTypedMessage, and DelegationController:signDelegation - this is core infrastructure.

2. New Intent Transaction Feature: A new intent.ts file adds CowSwap order signing capability, which is a new transaction type for intent-based bridge transactions.

3. Bridge Submission Changes: useSubmitBridgeTx.ts now routes intent transactions through a separate code path using handleIntentTransaction().

4. Transaction UI Changes: TransactionElement/index.js adds intent status mapping (SUBMITTED, PENDING, COMPLETE, FAILED) and modifies how bridge transaction status is displayed.

5. Package Changes (DEV-ONLY): package.json points to local file paths for bridge-controller, bridge-status-controller, and transaction-controller - this won't work in production and indicates this is development/testing setup.

6. Bridge API Points to localhost: BRIDGE_API_BASE_URL changed to localhost:3000 - clearly a dev setup.

The changes are high-risk because they modify:

• Core transaction controller messaging
• Transaction submission flows for bridges
• Transaction history lookup logic
• Transaction list UI rendering

Recommended tags:

• SmokeTrade: Directly tests bridge functionality (bridge-action-smoke.spec.ts exists)
• SmokeSwaps: Related swap functionality that shares infrastructure
• SmokeConfirmationsRedesigned: Transaction confirmation flows may be affected by the new intent transaction types and controller messenger changes
• SmokeAssets: Transaction element changes affect how transactions appear in activity view
