Subject: [PATCH] fix: repair cross-package test failures across ui, utils, and
 web

- api.ts: import the renamed useDebounce hook (was stale useThrottle)
- date.ts: format day as numeric (no leading zero), keep d/m/y order
- Button: forward aria-label to the DOM element for accessible name
- DataTable: use functional updater to fix stale-closure sort toggle
- tsconfig: reference already-installed bun-types so bun:test resolves
