Daniel Johnson 63c9653ed0 Port Lutris GUI from GTK 3 to GTK 4 ...

Migrate the entire GUI layer to GTK 4.10+. The app launches and displays
the game library (grid/list views with covers) without errors.

Key changes:
- gi.require_version: Gtk 3.0→4.0, Gdk 3.0→4.0, WebKit2→WebKit 6.0
- Container packing: pack_start/pack_end→append, container.add→append/set_child
- Remove show_all() (widgets visible by default in GTK 4)
- set_border_width→margins, get_style_context().add_class→add_css_class
- get_toplevel→get_root, Gtk.Window.list_toplevels→get_toplevels
- Event signals→controllers (button-press→GestureClick, key-press→EventControllerKey,
  focus-out→EventControllerFocus, delete-event→close-request)
- Gtk.Menu/MenuItem removed→PopoverMenu+Gio.Menu or Gtk.Button
- Gtk.FileChooserNative removed→Gtk.FileDialog (async, GTK 4.10+)
- Gtk.Clipboard.get→widget.get_clipboard()
- Gtk.EntryCompletion removed (not available in GTK 4)
- Gtk.StatusIcon/AppIndicator removed (GTK 3 only)→null object stub
- Dialog.run() removed→nested GLib.MainLoop compat for sync dialogs
- GtkBuilderDialog: builder.connect_signals removed
- CellRenderer do_render→do_snapshot bridge via snapshot.append_cairo
- gi_composites.py rewritten for GTK 4 template support
- All 6 .ui files converted (removed packing, visible props, GTK 3 widgets)
- CSS: fixed missing semicolons, updated color variable names
- Reset mypy baseline for GTK 4 stub mismatches (pygobject-stubs are GTK 3)

Deprecated but functional APIs kept for now (future phases):
- Gtk.TreeView, Gtk.IconView, Gtk.CellRenderer, Gtk.ListStore
- Gtk.ComboBox
