## PR-Codex overview
This PR focuses on refactoring the fetching logic for
`bCakeWrapperAddresses` and improving the usage of the `useV3FarmAPI`
hook by utilizing `useMemo` for better performance.

### Detailed summary
- In `fetcher.ts`, changed the mapping from `validReserveTokens` to
`validLpTokens`.
- Directly accessed `tokens.address` instead of using
`getV2LiquidityToken`.
- In `useV3FarmAPI.ts`, replaced `farms: farms ?? []` with `farms` for
cleaner code.
- Introduced `useMemo` to memoize `farms` based on `data`.
