Subject: [PATCH] fix: repair cross-package bugs causing test and type failures

- api.ts: import renamed useDebounce hook (was stale useThrottle) from @e2e/utils
- Button: forward aria-label to the button element for icon-only accessibility
- DataTable: fix stale closure so latest props/state are used on re-render
- date.ts: correct locale/format so day-first formatting is not confused with month
- tsconfig: add bun-types so bun:test type declarations resolve
