feat: Implement user tracking in projects

- Added user tracking features to the projects module, including:
  - Database schema updates to track project creator and assignee.
  - API enhancements for user management and project filtering by user.
  - UI components for user assignment in project forms and listings.
  - New query functions for retrieving users and filtering projects.
  - Security integration with role-based access and authentication requirements.

chore: Create utility scripts for database checks and project testing

- Added scripts to check the structure of the projects table.
- Created tests for project creation and user tracking functionality.
- Implemented API tests to verify project retrieval and user assignment.

fix: Update project creation and update functions to include user tracking

- Modified createProject and updateProject functions to handle user IDs for creator and assignee.
- Ensured that project updates reflect the correct user assignments and timestamps.
