Completed a comprehensive comparison of the Quotations module between RegalSolar and AppForSolar, covering both backend and frontend functionality. Reviewed controllers, services, routes, database schemas, email templates, and all quotation-related pages. Confirmed that AppForSolar already supports all existing RegalSolar quotation features, with additional improvements in tenant handling, customer document uploads after approval, TypeScript implementation, and user interactions. Enhanced the quotation table by updating the Acceptance Deadline column to display "Already Accepted" in green for accepted quotations, improving status visibility and user experience. Also verified that the notification API's 304 Not Modified response is normal caching behavior.
