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

- utils: re-export renamed useDebounce hook as useSearchDebounce for consumers
- utils: formatDate now uses unpadded day (d/MM/yyyy), e.g. 1/03/2024
- ui: Button forwards aria-label to the underlying <button> (WCAG 4.1.2)
- ui: DataTable sort toggle uses functional setState to fix stale closure
- tsconfig: add bun-types to compilerOptions.types to resolve bun:test typings
