Fixes #257: the Linux tray menu no longer opens in 26.11.1.

Cause

tray_manager 0.8.0 runs on nativeapi, whose Linux tray is a StatusNotifierItem. The panel draws the menu from the exported dbusmenu. NativeTrayPlatform.init set ContextMenuTrigger.none and opened the menu itself on click. On Linux:

• TrayIcon.openContextMenu() always returns false (nativeapi 0.5.2 up to the current core), so openMenu() throws Unable to open the tray menu.
• With trigger none, the item exports Menu = /NO_DBUSMENU and ItemIsMenu = false, so the panel has no menu to show. On GNOME a single click doesn't reach the app at all.

Change

lib/service/shared/menu/tray/platform.dart, Linux only:

• Use ContextMenuTrigger.clicked, so the item exports its dbusmenu with ItemIsMenu = true and the panel opens the menu on a left or right click.
• Ignore tray click events instead of calling onClick (which led to openMenu()). Some hosts still send Activate / ContextMenu alongside the exported menu. A debug log line records it.

Windows and macOS keep none + openContextMenu().

The panel's dbusmenu opened / closed events arrive as MenuOpenedEvent / MenuClosedEvent, so onMenuVisibility and the TrayService refresh hold while the menu is open still work. Item clicks arrive as MenuItemClickedEvent through the same listeners as before.

Verification

• Static: git diff --check passes. I didn't have a Flutter SDK on the test host, so flutter analyze / flutter test were not run, and I didn't build or run the patched app.
• Native layer, on Ubuntu 26.04.1, GNOME Shell 50.1 (Wayland), Ubuntu AppIndicators extension: a small C program used libcnativeapi.so from the 26.11.1 DEB the same way NativeTrayPlatform does.
  • Trigger none (current code): openContextMenu() = false, Menu = /NO_DBUSMENU, ItemIsMenu = false. This matches the installed 26.11.1.
  • Trigger clicked (this change): Menu = /StatusNotifierItem/Menu, ItemIsMenu = true, GetLayout returns the items. Sending dbusmenu Event opened, then clicked on an item, then closed, delivered MenuOpenedEvent, MenuItemClickedEvent and MenuClosedEvent in that order.
• Not yet checked: clicking the panel with a build of this branch, on GNOME and on KDE.
