Improve Change Pal dialog layout and replace compatibility checkbox with protocol selector

[Copilot]

The “Change Pal’s Information” dialog had inconsistent label/field alignment, and its last control exposed protocol behavior as a single compatibility checkbox. This updates the dialog to use a clearer aligned layout and surfaces protocol selection explicitly as AUTO, IPMSG, or IPTUX.

• Dialog layout

  • Switch the form body to a grid-based layout so labels and inputs align consistently.
  • Keep the existing fields and interactions intact while improving scanability of the dialog.

• Protocol selection

  • Replace the trailing compatibility checkbox with a Protocol combo box.
  • Map the UI directly to three modes:
    • AUTO: preserve detected/default compatibility behavior
    • IPMSG: force IP Messenger-compatible behavior
    • IPTUX: force iptux protocol behavior

• Model behavior

  • Add explicit protocol override state to PalInfo instead of overloading a boolean UI control.
  • Keep existing compatibility checks working by resolving them from the selected protocol mode.

• Dialog robustness

  • Guard the icon-selection path so applying dialog changes does not fail when no face-picture item is selected.

Example of the new protocol model behavior:

palInfo.setProtocol(PalProtocol::AUTO);   // use detected compatibility
palInfo.setProtocol(PalProtocol::IPMSG);  // force non-iptux behavior
palInfo.setProtocol(PalProtocol::IPTUX);  // force iptux behavior

• Fixes GUI improvement: "Change Pal's Information" #571

this part is weird, you should change the Pal model, and the model change trigger the UImodel change

Addressed in 1377695. I restored the face-picture button’s combo-box binding in the dialog and added a regression test for that wiring so the Change Pal dialog no longer gets stuck after using the updated form.
