Root bun test now passes 13/13 (it was 9 failing). tsc --noEmit is clean.

• apps/web/src/lib/api.ts: it imported useThrottle, which had been renamed to useDebounce in packages/utils. It now imports useDebounce and still re-exports it as useSearchDebounce.
• packages/ui Button: the component now passes aria-label through to the rendered button. If an icon-only button has no label, it falls back to string children, then to "Button" as a placeholder. Outside production it also logs a console.warn, which the test name and the component docstring both asked for.
• packages/utils formatDate: builds the date as unpadded day, padded month, then year (e.g. 1/03/2024), which is what the test expects. This changes visible output for days 1–9, which used to render as 01/03/2024.
• bunfig.toml: the root file used environment = "happy-dom", which isn't a valid Bun option, so no DOM was being set up. It now preloads packages/ui/test/setup.ts.
• tsconfig.json: added bun-types to types so the bun:test imports type-check. bun-types was already a devDependency.

Assumptions

• No test files were changed and no dependencies were added.
• The DataTable stale-closure test passes once the DOM setup is fixed. handleSort is recreated on every render, so DataTable.tsx was left unchanged.
• tsc isn't on PATH in this environment, so I ran the type check with bunx tsc --noEmit.
• The "Button" fallback label exists only because the test requires some non-empty label. Callers should still pass a meaningful aria-label.
