Add project management features and enhance database schema

- Introduced a new `server_projects` table to manage project details.
- Updated the `vps` table to include a foreign key reference to `server_projects`.
- Enhanced the API to support project-related data retrieval and manipulation.
- Implemented project filtering in the Reports and VPS pages.
- Added project selection functionality in the UI for better resource management.
- Improved data seeding and migration scripts to accommodate new project structure.
