KeysPage::new now takes a single AppContext that owns parent_window,
toast_overlay, and the shared daemon Rc<RefCell<Option<Daemon>>>. Phases
9, 10, 11, and 12 GUI tab will all consume this struct.

Adds enroll_dialog::present which opens an adw::AlertDialog with a spinner
and races the EnrollOwn call against the EnrollmentFailed signal stream:
- Call returns Ok(_cred) -> close dialog, fire on_success refresh callback.
- Call returns Err -> swap dialog body to the user-message form.
- Signal arrives first -> swap to the signal payload (faster than waiting
for the call's typed Err to traverse the bus).
KeysPage::start_enroll wires the activated row to present(), passing the
parent window for modal anchoring and a refresh closure as on_success.
Plan deviation: AlertDialog is libadwaita v1_5-gated, so gui/Cargo.toml
enables that feature. Targets Ubuntu 24.04+ (libadwaita 1.5).
KeysPage::new spawns the connect-and-render flow on glib::MainContext::
spawn_local. On success it shows a placeholder PreferencesPage (Task 5
fills in the list); on failure it shows StatusPage with a Retry button
that re-runs the connect attempt.
main.rs installs the multi-thread tokio runtime guard before app.run()
so zbus's tokio futures execute correctly when polled by glib.
Layout deviation from plan: ToolbarView is libadwaita v1_4-gated; the
project sticks with gtk::Box vertical for portability (commit c6a5e94
established this pattern).
