Pull Request Overview
This PR adds a new Christmas countdown app to the badge that displays the number of days remaining until Christmas. The app features animated falling snowflakes as a visual backdrop and uses NTP to sync the system time over WiFi.
Key Changes:
- Created a Christmas countdown app with animated snowflakes and date-based countdown functionality
- Implemented NTP time synchronization with retry logic for reliable date retrieval
- Added WiFi connection handling with SSID scanning and timeout mechanisms

The hardcoded year range (2025-2100) uses a magic number for the upper bound. Consider using a constant like MAX_VALID_YEAR = 2100 to make this value more maintainable and its purpose clearer.

The screen dimensions (80 for center X, various Y positions) are hardcoded throughout the code. Consider defining constants like SCREEN_CENTER_X = 80 and SCREEN_WIDTH = 160 to improve maintainability and make the code self-documenting.

The Matrix import is unused in the code. Consider removing it to keep imports clean.

The interesting thing in this app is that it shows more examples of how to configure your network, as well as how to use NTP to get a good date set as the device doesn't store date and constantly resets to 01 Jan 2021 on reboot.
