Native Desktop Client for RAC Windows RDP with Fullscreen & Multi-Screen Support

**Is your feature request related to a problem? Please describe.**
When using RAC Windows RDP sessions via the browser, the experience is not optimal for daily remote work. The fullscreen functionality does not work properly for me, and at times, input is mistakenly captured by the browser instead of the VDI session. Additionally, multi-screen support is not available, which significantly limits productivity for users who rely on multiple monitors. This leads to usability issues and reduces efficiency when working remotely.

**Describe the solution you'd like**
I would like to have a dedicated desktop client for RAC Windows RDP sessions, similar to what Omnissa Horizon offers. A native client would provide a more seamless experience, ensuring proper fullscreen functionality, multi-screen support, and better input handling, thus improving the overall remote work experience.

**Describe alternatives you've considered**

Using the browser-based solution, but as mentioned, it does not provide an optimal fullscreen experience, lacks multi-screen support, and causes input issues.

Using third-party RDP clients, but integration with Authentik’s authentication system may not be as smooth.

Exploring different browsers to see if the issue persists, but the problem remains across different environments.
