Subject: [PATCH] fix: resolve all failing tests and type errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix auth middleware case-sensitivity: 'post' → 'POST' in public methods
- Fix User type field name: 'userName' → 'username' for consistency
- Fix users route: replace undefined badRequest with proper Hono response
- Implement pagination utility (paginate function) per test expectations
- Add bun-types to tsconfig for proper type resolution
