Implement Grade Data Management Functionality

[TKanX]

Description:

Implementation of a complete grade data management system, including the following features:

• Semester-level hierarchical data management (terms → courses → categories → tasks).
• Basic academic data calculations (e.g., total scores, GPA).
• Import/export functionality for academic data.
• Integration with user settings for seamless data management.

The implementation includes both backend endpoints and frontend components to ensure a comprehensive and user-friendly grade management process.

Tasks:

Backend:

1. Grade Management API Endpoints:
   • Create Semester:
     • Endpoint: POST /grades
     • Create a new semester with basic details.
   • Get All Semesters:
     • Endpoint: GET /grades
     • Fetch a list of semesters with basic details.
   • Get Semester Details:
     • Endpoint: GET /grades/:id
     • Fetch detailed data for a specific semester, including nested courses, categories, and tasks.
   • Update Semester Data:
     • Endpoint: PUT /grades/:id
     • Replace all data for a specific semester, including courses, categories, and tasks.
   • Partial Update of Semester Data:
     • Endpoint: PATCH /grades/:id
     • Apply JSON Patch updates to specific elements within a semester.
   • Delete Semester:
     • Endpoint: DELETE /grades/:id
     • Delete a specific semester by ID.
   • Export Specific Semester Data:
     • Endpoint: GET /grades/:id/export
     • Export detailed data of a specific semester as a JSON file.
   • Export All Semesters Data:
     • Endpoint: GET /grades/export
     • Export all semesters' data as a JSON file.
   • Import Semester Data:
     • Endpoint: POST /grades/import
     • Bulk import multiple semesters with nested data (courses, categories, tasks).
   • Data Validation:
     • Ensure input validation for all endpoints, especially for data consistency across nested elements (e.g., tasks should not conflict with calculated category scores).

Frontend:

1. Create Components:

   • Semester Switcher:
     • Floating component for switching between semesters.
     • Includes basic management options (e.g., add, delete, rename semesters).
   • Semester Overview:
     • Display aggregated semester information, such as total GPA and scores.

2. Create Pages:

   • Semester Management Page:
     • Multi-level data management interface for semesters, courses, categories, and tasks.
     • Allow users to add, edit, and delete elements within the hierarchy.
     • Provide real-time score calculation and GPA display.
   • Settings Page (Update Existing):
     • Add options for exporting and importing academic data.
     • Integrate import/export functionality with the backend APIs.

3. Features:

   • Data Visualization:
     • Show calculated data such as GPA, total scores, and percentages.
   • Data Consistency Checks:
     • Ensure data integrity when adding or editing nested elements (e.g., tasks updating category scores).

4. Integration with Backend:

   • API Integration:
     • Connect all frontend components to their respective backend endpoints.
