fix: branded splash back, wider month range, December title bug

- Restore the branded in-app splash (Calendarr name + icon + © Scarriffle),
  held until the first events load; logo sized to match the system splash so it
  doesn't visibly jump, name/copyright fade in
- Month calendar now scrolls 10 years back / 50 years ahead (was ±18 months)
- Fix month/quarter title: use Month.getDisplayName instead of the 'LLLL'
  pattern, which dropped the month name (e.g. December showed only '2026')
