Subject: [PATCH] fix: resolve cross-package test and type failures

- ui: register happy-dom in root bunfig preload so root-level bun test injects DOM globals
- ui(Button): wire declared aria-label prop onto rendered button element
- ui(DataTable): fix stale-closure in sort toggle via functional state updater
- utils(date): format en-AU as D/MM/YYYY (4-digit year) instead of zero-padded numeric
- web(api): update import/re-export for renamed useThrottle -> useDebounce hook
