Integrate mcdvoice-style Customer Feedback System into D-Tools

It would be great to have a built-in customer feedback module in D-Tools, inspired by systems like McDonald’s [mcdvoice](https://www.mcdvoice.site). This feature could allow clients to quickly share their experience, rate services, and provide structured input after project completion. Having a simple, survey-style interface would help gather valuable insights, improve service quality, and build stronger client relationships—all within the D-Tools environment.
