E2E Test Selection:
All changes are contained within the Bridge/Swap Batch Sell feature area. The PR wires up real quote fetching for the Batch Sell flow, replacing placeholder data with actual BridgeController integration. Key changes include:

1. Redux slice (CRITICAL): Added batchSellSourceTokenAmounts state, new actions, and selectBatchSellQuotes selector wrapping the base controller selector.
2. Bridge selectors: Added selectBatchSellSourceWalletAddress for wallet address resolution in batch sell.
3. BatchSellReview: Major refactor integrating real quote data via useBatchSellQuoteRequest and useBatchSellQuoteData hooks, replacing all placeholder values.
4. BatchSellPercentageSlider: Changed minimum snap point from 0% to 25% - behavioral change.
5. BatchSellTokenSelect: Now initializes source token amounts, destination token, and slippages before navigating to review.
6. New hooks: useBatchSellQuoteRequest and useBatchSellQuoteData implement the actual quote fetching and formatting logic.

The changes are scoped to the Bridge/Swap Batch Sell feature. SmokeSwap covers bridge and swap functionality including the bridge action tests. Per SmokeSwap tag description, SmokeConfirmations must also be selected since transaction confirmations are part of the swap/bridge flow. No other test areas (accounts, network, identity, snaps, etc.) are affected by these changes.

Performance Test Selection:
The changes are focused on the Batch Sell feature within Bridge/Swap - adding quote fetching logic, new Redux state fields, and UI wiring. While there is some new data processing (quote formatting, BigNumber calculations), these are not in performance-critical paths like app startup, account list rendering, or login flows. The changes don't affect any of the performance test areas (account list, onboarding, login, swaps performance, app launch, asset loading, predict, or perps). No performance tests are warranted.
