Subject: [PATCH] fix: repair cross-package bugs so all tests pass

- fix stale useThrottle import in apps/web/src/lib/api.ts to use
  useDebounce, keeping the useSearchDebounce public alias intact
- forward aria-label on icon-only Button for an accessible name (WCAG 4.1.2)
- use en-AU dateStyle:short in formatDate so day 1 is not confused with
  month 1 (day-first, non-ambiguous ordering)

No test files modified, no new dependencies. All 13 tests pass across
packages/ui, packages/utils, apps/web; tsc clean (except pre-existing
bun:test env resolution errors).
