fix(notifications): quiet hours start and end while the app stays open (#325)

useNotificationsQuiet evaluated the quiet-hours window (and the
"Pause notifications" expiry) only at render time, and the long-lived
message/invite notifiers rarely re-render, so someone leaving Lotus open
overnight with quiet hours 22:00–07:00 got every sound all night (and a
30-minute pause could outlast itself). The hook now re-evaluates every
30 s.

Verified headless (notifications granted, window unfocused): quiet
hours set to start ~75 s after the app opened; a DM before the window
notified; one inside the window, with the app left alone: before it
still notified, now it's silent.

Fixes #325
