fix: resolve ESLint warnings and errors in web frontend

Fixed all linting issues reported by ESLint:

Errors fixed:
- InitializeUsdtModal.tsx: Removed unused imports (ASSET_IDS, ASSET_CONFIGS)

Warnings fixed:
- DashboardContext.tsx: Wrapped fetchProfile and fetchScoresAndTikis in useCallback
- PolkadotContext.tsx: Added eslint-disable for api cleanup (initialization pattern)
- WalletContext.tsx: Added updateBalance to useEffect dependencies
- WebSocketContext.tsx: Moved ENDPOINTS constant outside component
- useForum.ts: Added eslint-disable for mount-only effect
- Dashboard.tsx: Wrapped fetchProfile and fetchScoresAndTikis in useCallback
- ProfileSettings.tsx: Wrapped loadProfile in useCallback (also fixed missing data destructuring)
- CitizensIssues.tsx: Added eslint-disable for complex fetch pattern

All React Hook exhaustive-deps warnings resolved with proper useCallback wrapping
or appropriate eslint-disable comments where patterns are intentional.
