[Feature] Ability to set FreeRDP window mode and resolution

[criostage]

Feature Description

This feature would let us choose whether the Windows Desktop app (used to RDP into the container desktop) launches in windowed or full-screen window mode. Additionally, it would be very useful to define the resolution of that window.

Use-Case

This feature would greatly improve usability when working with the Windows desktop app, as it would make tasks like copying content directly from the desktop into the container much easier. At the moment, using an ultra‑wide screen is frustrating whenever I need to access the desktop environment to adjust settings or when I want to run Linux and Windows side by side.

Proposed Implementation

I attempted to duplicate the "Windows Desktop" app and use FreeRDP arguments in this app argument's (mentioned in this github issue), but unfortunately that this didn’t work as expected. Implementing these options would allow to configure FreeRDP window making it easier to use the desktop mode depending on the user's preferences. These 2 new options could be to placed within the Configuration Menu, alongside the existing Display Scaling options, or alternatively make them accessible directly from the application icon (when editing it) in the Apps list as 2 drop down menus.
