comprehensive maintenance reports with configurable parameters, date ranges, and filters\n2. **getReportData**: Retrieves report data by ID or query parameters with pagination support\n3. **submitFieldReport**: Handles field inspection reports with automatic maintenance request creation for high-priority issues\n\nThe API includes proper validation, error handling, and follows the established codebase conventions with trilingual comments and Supabase integration patterns."
