Subject: [PATCH] fix: resolve all test failures and type errors across api and
 shared packages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix User type field name: userName → username (shared/types.ts)
- Implement paginate() utility with proper slicing and metadata (shared/utils/pagination.ts)
- Fix auth middleware case-sensitivity: normalize HTTP method to uppercase (api/middleware/auth.ts)
- Fix missing import and field name usage in users route handler (api/routes/users.ts)
