Issue 102 | Full user profile management (no pfp)

[Flapjacck]

This pull request introduces several improvements to user profile, preferences, and password management, with a focus on input validation, controller simplification, and API consistency. The backend now uses Zod schemas for request validation, reducing manual checks and improving maintainability. New endpoints for changing passwords and fetching/updating user profiles and preferences have been added, and the frontend is updated to use these endpoints. Below are the most important changes grouped by theme:

Backend: User Controllers and Validation

• Introduced Zod-based validation schemas in userValidators.ts for profile updates, preferences, and password changes, replacing manual validation logic in controllers.
• Refactored updateProfile and updatePreferences controllers to use their respective schemas, simplifying the update logic and ensuring consistent input handling. [1] [2] [3]
• Added new controllers: changePassword (for authenticated users to change their password) and getProfile (to fetch the current user's profile). [1] [2]

Backend: Routing and API Structure

• Updated userRoutes.ts to add new endpoints for profile, preferences, and password actions, and reorganized route order for clarity and usability. [1] [2] [3]
• Exported new controllers in the user/index.ts barrel file.

Frontend: API Integration

• Updated frontend authApi.ts to use /users/profile for fetching the current user, and added helpers for updating profile, changing password, and managing preferences. [1] [2] [3]
• Added comments in AuthProvider.tsx to clarify endpoint usage for fetching user data.

Miscellaneous

• Adjusted logo size in DashboardHeader.tsx for better UI consistency. [1] [2]
• Updated tsconfig.json to exclude test files from compilation.
• Added a comment in user.ts regarding future profile image upload support.
