Subject: [PATCH] fix: resolve all failing tests and type errors

- Auth middleware: case-insensitive HTTP method comparison for public routes
- Shared types: rename userName to username for consistency with API/tests
- Users route: add missing badRequest import from errors lib
- Pagination utility: implement paginate function with proper slicing
- tsconfig: add bun-types to resolve bun:test and process type errors
