✨ Major Changes

🔧 Logging System Rebuild

• Logging is now split into serial and file-based CSV logging.
• Serial logging is explicitly enabled in firmware for debugging (e.g. when connected to a PC), and disabled in production to reduce system load.
• Debug logs are now saved as CSV (instead of .txt) for better usability.
• Log entries now include a log level (e.g. debug, info, warning, error).
• Logging behavior is now controlled via log level setting instead of a simple true/false flag.
• Logs are displayed newest first and now visually improved in the WebUI.
• Added escaping function to ensure log messages are safely written in CSV format.

🧠 Backend Enhancements

• modbusServeTask is now pinned to Core 1 to avoid timeouts caused by IO overload.
• Sensor switched from HDC1080 to BME280 (adds pressure readings).
• Added pressure threshold as a new configurable setting.
• Reduced serial output to minimize unnecessary logging and CPU load.
• Added restart reason display on the device info page.
• PlatformIO lib_deps are now cleaned up and better structured.

🌐 Web Interface Updates

• WebUI now displays pressure value.
• Logs are shown using a visually improved layout.
• Restart button now uses a confirmation modal.
• Fix: index route now properly redirects instead of showing /404.
• Added dynamic SVG handling for door states when the door is not connected.
• Translations updated: minor fixes, removed btn-light, and added support for dynamic string translation.
• New direct link added to verify the serial number from the info page.

📡 Home Assistant / MQTT Integration

• Added MQTT pressure sensor support.
• Added new MQTT sensor for detailed door state (open, closed, stopped, half, venting) in addition to existing cover entity.
• External sensors (connected via I2C) are now:
  • Pushed to Home Assistant.
  • Dynamically handled in WebUI.
  • Can now be combined if multiple of the same type are connected.
