byGalax 05870ef8fa feat(call): split resolution/fps in share picker + restore window state after fullscreen
ScreenSharePickerModal now exposes Auflösung (Auto · 720p · 1080p · 1440p
· 4K) and FPS (30 · 60) as separate pill rows instead of bundled quality
presets — users can pick "1440p · 30 fps" or "4K · 30 fps" which the old
preset list didn't surface. The underlying screenShareSettings framerateOverride
slot already existed; the modal just stopped resetting it to null on every
start and now plumbs the chosen FPS through to startScreenShare.

Cinema-mode fullscreen on Windows had two defects:

1. Maximized → fullscreen left the taskbar drawn on top of the window
   because DWM kept the maximized work-area constraints. We now unmaximize
   first so DWM recomposes cleanly and setFullScreen actually covers the
   whole monitor including the taskbar strip.

2. Esc out of cinema came back as a small floating window even when the
   user had been maximized before clicking the Vollbild button — the
   unmaximize from (1) was never undone. We now memo the pre-fullscreen
   maximized flag per window-id and call win.maximize() once the
   leave-full-screen event has fired.

// the way Tauri's appWindow.setFullscreen used to.
