Subject: [PATCH] fix: repair cross-package bugs and test DOM/type config

- api.ts: import useDebounce (renamed from useThrottle) and re-export as useSearchDebounce
- Button: set aria-label for icon-only buttons for accessible name
- DataTable: use functional state updater to fix stale-closure sort direction
- date.ts: use en-AU dateStyle:'short' so day/month order follows locale
- bunfig.toml (root): register happy-dom + setup preload so component tests get a DOM at root-level runs
- tsconfig.json: add bun-types so 'bun:test' resolves
