- 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

/**
|
|
* CalendarActivity - Automated calendar image fetch and display
|
|
*
|
|
* This activity is triggered on timer wake (not power button wake).
|
|
* It connects to WiFi, fetches a BMP image from a configured URL,
|
|
* saves it as the sleep screen, and returns to deep sleep.
|
|
*
|
|
* Flow:
|
|
* 1. Load saved WiFi credentials
|
|
* 2. Connect to WiFi (timeout: 30s)
|
|
* 3. HTTP GET image from configured URL (timeout: 60s)
|
|
* 4. Save image to /sleep.bmp on SD card
|
|
* 5. Render sleep screen
|
|
* 6. Schedule timer wake for next refresh
|
|
* 7. Enter deep sleep
