feat: Refactor project creation and management to support modular project types

- Updated project creation modal to allow selection of optional modules (Sound and Vibration Monitoring).
- Modified project dashboard and header to display active modules and provide options to add/remove them.
- Enhanced project detail view to dynamically adjust UI based on enabled modules.
- Implemented a new migration script to create a `project_modules` table and seed it based on existing project types.
- Adjusted form submissions to handle module selections and ensure proper API interactions for module management.
