feat: Implement project search functionality and task management features

- Added search functionality to the Project List page, allowing users to filter projects by name, WP, plot, or investment number.
- Created a new Project Tasks page to manage tasks across all projects, including filtering by status and priority.
- Implemented task status updates and deletion functionality.
- Added a new Task Template Edit page for modifying existing task templates.
- Enhanced Task Template Form to include a description field and loading state during submission.
- Updated UI components for better user experience, including badges for task status and priority.
- Introduced new database queries for managing contracts and projects, including fetching tasks related to projects.
- Added migrations to the database for new columns and improved data handling.
