Implement CiviCRM middleware form with stage-based visibility

- Initialize Next.js project with Tailwind CSS
- Create CiviCRM APIv4 integration layer
- Implement stage-based form visibility (stages 0-5)
- Add field mapping configuration for CRM-to-form linking
- Create API routes for data retrieval and submission
- Record form submissions as CiviCRM activities
- Support dynamic contactId and orgId via URL parameters
- Ensure robust form state management with react-hook-form
