gsxdsm 284feeaf11 FN-9092: prevent model menus from dismissing host dialogs ...

Keep portaled model-menu interaction from propagating to host dialog dismissal.

- Mark model-menu portal surfaces and stop their pointer events from reaching dialog backdrops.
- Apply the dismissal guard across agent, chat, floating-window, and model-selection dialogs.
- Close enabled overlays on valid touch taps while suppressing duplicate compatibility mouse closes.
- Add desktop and mobile regression coverage for portal-host dismissal behavior.
