- Create `getLocalKeysForAccounts` in `store.js` that performs a batch fetch of all local keys grouped by `accountId`. - Update `PoolController.getPoolData` to call this new function once before iterating through `allAccounts`, replacing `N` individual queries to `store.getLocalKeys` with 1 batch query. - Tests updated and verified.

💡 What: Created a new batched function
store.getLocalKeysForAccountsthat uses anINdatabase query to fetch keys for all accounts and groups them byaccountId. Replaced the individual await calls inPoolController.getPoolDatawith a single batch fetch using thelocalKeysMap.🎯 Why: Iterating over
allAccountsand executing a database call insidePromise.allSettled(allAccounts.map(async ...))leads to an N+1 query problem when loading the application pool data. This places unnecessary load on the database when the number of accounts increases.📊 Impact: Decreases database queries for this endpoint from O(N) to O(1), improving query latency and reducing load.
