Summary

Fixes all failing tests and type errors in the monorepo. The suite now reports 13 pass / 0 fail and tsc --noEmit exits cleanly (0 errors).

Four cross-package bugs (plus a type-config gap) were fixed:

• Renamed hook reconciled — packages/utils now exports useSearchDebounce (re-export of useDebounce), and apps/web/src/lib/api.ts imports useSearchDebounce instead of the stale useThrottle. This resolved both the failing api module tests and the TS2305 type error.
• Button accessibility — the icon-only Button (packages/ui) now forwards aria-label so it has an accessible name; when no label is provided it no longer emits an empty aria-label="".
• Date formatting — packages/utils/src/format/date.ts corrected to produce en-AU day/month order with a non-zero-padded day (e.g. 1/03/2024, not 01/03/2024).
• bun:test type resolution — added the already-installed bun-types package to compilerOptions.types in tsconfig.json so test files type-check. No new dependency was added (the package was already present in node_modules).

The DataTable controlled re-render (stale-closure) test was verified to pass; no change was required there.

Verification

```
bun test packages/utils/test packages/ui/test apps/web/test --preload ./packages/ui/test/setup.ts

13 pass, 0 fail

./node_modules/.bin/tsc --noEmit

exit 0

```

Assumptions / constraints honoured

• No test files modified and no new dependencies added, per task constraints.
• Treated the canonical test invocation as the repo's `npm test` script (which includes `--preload ./packages/ui/test/setup.ts` to register happy-dom). Running bare `bun test` without that preload yields spurious `document is not defined` failures; those are an invocation artefact, not source bugs.
• `bun-types` was already resolvable in `node_modules` (v1.3.14), so registering it in `tsconfig` is a config change, not a dependency addition.
• For icon-only buttons with no `aria-label`, kept a sensible fallback accessible name rather than rendering an empty string (WCAG 4.1.2).
