Note

Introduce usePerpsMarketFills to merge WebSocket and REST fills (filtered, deduped, sorted) and switch PerpsMarketTradesList to use it.

• Hooks:
  • Add usePerpsMarketFills that merges WebSocket (usePerpsLiveFills) and REST (getOrderFills) data, filters by symbol, deduplicates by orderId-timestamp, sorts desc by timestamp, and exposes refresh, isInitialLoading, isRefreshing.
  • Export usePerpsMarketFills from hooks/index.ts.
• UI:
  • Update PerpsMarketTradesList.tsx to use usePerpsMarketFills; remove in-component filtering/sorting and keep limiting via PERPS_CONSTANTS.RECENT_ACTIVITY_LIMIT.
• Tests:
  • Add usePerpsMarketFills.test.ts covering symbol filtering, data merging precedence, sorting, REST fetching/error handling, refresh behavior, throttling, and symbol changes.

The changes are entirely contained within the Perps (Perpetuals trading) feature directory (app/components/UI/Perps/). The PR introduces:

1. A new hook usePerpsMarketFills.ts that combines WebSocket and REST API data for fetching market-specific fills
2. Comprehensive unit tests for the new hook (535 lines of tests)
3. An update to PerpsMarketTradesList.tsx to use the new hook instead of usePerpsLiveFills
4. Export of the new hook in the hooks index file

The changes are well-isolated:

• The new hook is only used by the modified component
• The component is only used within Perps views
• No core modules, controllers, or critical infrastructure is affected
• The changes include thorough unit test coverage

This is a feature-specific enhancement to the Perpetuals trading functionality with no impact on other wallet features. Only the SmokePerps tag is needed to verify this change.
