Pull request overview

This PR adds a moderator flow to the platform, covering both backend and frontend. On the backend, it introduces a moderator login endpoint, a moderator query repository, the ability for moderators to change a teacher's status (draft/pending/active/rejected/blocked), and role-based access control updates to existing endpoints. On the frontend, it adds a dedicated moderator login page that reuses the existing LoginForm component.

Changes:

• New moderator authentication and teacher-status-management APIs, including DB schema, types, repository, service, and controller
• Role-type refactoring (Role broadened to include "moderator", a narrower UsersRole introduced for student/teacher contexts)
• New moderator login page on the frontend, reusing existing login UI with moderator-specific conditional rendering
