Chris Korhonen 50b2a37fb7 feat: Add Calendar Mode for automated e-ink calendar display
- Add CALENDAR sleep mode that bypasses /sleep/ directory to ensure calendar image displays
- Implement CalendarActivity state machine: WiFi→NTP→HTTP fetch→save to /sleep.bmp→deep sleep
- Add NTP time sync and fetch timestamp persistence in CrossPointState
- Show visual status feedback during calendar fetch ("Connecting...", "Fetching...")
- Add calendar settings UI: toggle, refresh hours (1-24h), "Test Calendar Now" action
- Fix hardware button sleep to display calendar when calendar mode enabled
- Graceful fallback: if fetch fails but cached image exists, use cached; otherwise use default screen
