Subject: [PATCH] fix: resolve 4 cross-package bugs causing test failures

- Fix renamed hook: re-export useDebounce as useSearchDebounce in api.ts
- Fix date format: use 'd/MM/yyyy' (no zero-padded day) in date utility
- Fix stale closure: use functional setState in DataTable sort handler
- Fix a11y: spread aria-label prop through Button component
- Fix DOM environment: configure happy-dom preload in root bunfig.toml
