ESPTimeCast Firmware 1.0.1 - Patch Release

• ESP32 auto pin handling: Improved board detection and automatic MAX7219 pin configuration for ESP32 variants.

• Reliable Web UI update mechanism: Replaced size-only validation of /index.html with content comparison to ensure HTML updates correctly, even when file size remains unchanged.

• AP-mode SSID/Password bug: Saving in AP mode now preserves the correct SSID and password, preventing the device from getting stuck in AP mode.

• AP-mode loop refactor: Display animation and web server handling optimized for better responsiveness and stability.

• Web UI updates: factory_reset and upload endpoints updated to match the new design. Small UI improvements.

⸻

Notes:

• Users experiencing AP-mode issues should reselect their WiFi and re-enter their password once to restore STA mode.

• Patch release only; no new features added.
