Subject: [PATCH] fix: repair cross-package bugs so all tests and typecheck
 pass

- utils: alias useDebounce as useSearchDebounce; reconcile stale useThrottle import in apps/web/src/lib/api.ts
- ui/Button: pass aria-label through to icon-only buttons with a sensible fallback
- ui/DataTable: use functional state updater to fix stale-closure sort toggle
- utils/date: use en-AU dateStyle:short so day is day-first without leading zero
- tsconfig: reference already-installed bun-types to resolve bun:test type errors
