feat: open the saved recording's folder when its notification is clicked

The "Recording saved to <path>" desktop notification is now clickable:
activating it opens the default file manager at the file's containing folder
(and highlights the file where the file manager supports it).

- Add an app.open-folder action (string target = file path) that uses
  GtkFileLauncher.open_containing_folder() — portal-backed, so it works on
  both X11 and Wayland.
- The saved-recording GNotification sets that action as its default action,
  and the in-app AdwToast gains a matching "Open Folder" button.

send_notification() gains a send_notification_full() variant carrying the
optional path; all other notifications are unchanged.
