feat(users): implement full user management CRUD

API endpoints (app/api/v1/admin/users.py):
- GET /users: Paginated list with search and filters
- POST /users: Create new user
- GET /users/{id}: Get user details with related counts
- PUT /users/{id}: Update user information
- PUT /users/{id}/status: Toggle active status
- DELETE /users/{id}: Delete user (with ownership check)

Pydantic schemas (models/schema/auth.py):
- UserCreate: For creating new users
- UserUpdate: For updating user information
- UserDetailResponse: Extended user details with counts
- UserListResponse: Paginated list response

Frontend:
- Updated users.html with server-side pagination and filters
- New user-create.html/js for user creation form
- New user-detail.html/js for viewing user details
- New user-edit.html/js for editing users

Routes added for user create, detail, and edit pages.
