feat: Add comprehensive authentication system with user management

- Add 4 user accounts (admin, system, researcher1, researcher2) with role-based permissions
- Implement session-based authentication with 8-hour timeout
- Add login page with elegant design and account selection
- Integrate authentication middleware into all API endpoints
- Add user info display and logout functionality in headers
- Implement tree ownership tracking with created_by field
- Add edit/delete permissions based on user roles and tree ownership
- Enhance tree list with user info and action buttons
- Update map view with authentication and elegant tree tooltips
- Add comprehensive edit/delete functionality with permission checks
- Implement tree management in both form and map interfaces
- Add enhanced popup details with action buttons in map view
- Include user greeting and role display in both interfaces
- Add form edit mode with cancel functionality
- Secure all file uploads and API endpoints with authentication
- Maintain backward compatibility while adding new features
