🎨 Palette: Enhance UX and Keyboard Accessibility in Multiple Entry Dialog

[Zee2401]

💡 What: Added button mnemonics (underline=0 for Ok and Cancel), Escape key binding, Alt+O/Alt+C shortcuts, and WM_DELETE_WINDOW protocol handler to scripts/o3de/o3de/ui/multiple_entry.py.
🎯 Why: Improves keyboard accessibility and guarantees clean dialog dismissal via keyboard or window manager controls.
♿ Accessibility: Underlined mnemonics, Escape dismissal, and Alt-accelerators for keyboard-only interaction.
🧪 Tests: Added unit test in test_export_project.py to headlessly verify input initializations, keyboard shortcuts, and window close handlers.
