Add system tray, shutdown-after-finish scheduler, repoint updater

- src/tray.rs: system tray with show/hide/quit menu, left-click
    toggles main window visibility (minimize-to-tray parity with v1).
  - src/shutdown.rs: 60s countdown with per-second 'shutdown-countdown'
    event; sleep/shutdown/restart via rundll32/shutdown on Windows,
    cancel-aware.
  - cancel_shutdown + set_shutdown_after_finish commands now drive the
    scheduler so the renderer's existing countdown UI works unchanged.
  - Cargo features + tray-icon + image-png added.
  - Updater pointed at new Gitea repo Administrator/Multi-Hoster-Upload-2.
