feat: Add user tracking to project tasks and notes

- Implemented user tracking columns in project_tasks and notes tables.
- Added created_by and assigned_to fields to project_tasks.
- Introduced created_by field and is_system flag in notes.
- Updated API endpoints to handle user tracking during task and note creation.
- Enhanced database initialization to include new columns and indexes.
- Created utility functions to fetch users for task assignment.
- Updated front-end components to display user information for tasks and notes.
- Added tests for project-tasks API endpoints to verify functionality.
