v1.7: fix widget losing data after screen lock/reboot

Two root causes:
- Alarms don't survive reboot — BootReceiver now restarts alarm + triggers
  an immediate fetch on BOOT_COMPLETED
- onUpdate() drew from cached prefs but never fetched fresh data — now
  triggers an immediate refresh so the widget is live on every launcher redraw
