fix: tray icon path for Flatpak and titlebar double-click maximize

- Fix Flatpak tray icon path (com.blitzfc.qbz, not com.blitzkriegfc.qbz)
- Fix titlebar double-click: prevent JS handler from firing on native
  drag regions, which caused double toggleMaximize (maximize then
  immediate restore)
- Improve tray click handlers to properly detect minimized state
