fix(notifications): in-app toasts no longer need browser notification permission (#324)

notify() shows an in-page toast while the window is focused and only
falls back to an OS notification otherwise, but both message and invite
notifications were gated on Notification.permission === granted. Anyone
who declined (or was never asked) heard the ping with nothing on screen.
Gate only the OS path on the permission.

Fixes #324
