Update searchInstructors endpoint to accept courseId parameter and filter out the requesting instructor and instructors already assigned to the course. Add email_verified_at field to UserResponse type and include it in auth and user service responses.
Update login endpoint to return consistent API response structure with code, message, and data fields. Wrap token, refreshToken, and user data inside a data object to match the standardized response format used across other endpoints.
Add separate frontend URL environment variables for student and instructor portals. Update password reset and email verification services to route users to the appropriate frontend based on their role (INSTRUCTOR vs STUDENT).
