feat: Live Notifications (rename, rework)

[austinkimchi]

Describe the solution you'd like

1. Change UI label:
   Currently: Live Smart Alarm Updates
   New: Live Notifications Updates
2. UI has no padding, some text is clipped
3. Smart alarm appears too early in the UI
   Either:
   Show before x hr x min before "predicted bedtime" (which we don't have and need to implement)
   Allow user to manual set what time to show
4. Needs better information on the smart alarm.
5. Allow users to customize live smart alarm?

Needs fix
New mode Auto Smart Alarm needs change in label to monotoring starts at xx:xx am.
