Pull request overview

This PR bundles several small functional updates across the firmware, mainly improving JSON safety in network responses, extending DHT11-derived environmental reporting, and adding an optional “reboot after save” flow for configuration.

Changes:

• Add JSON string sanitization and apply it to WiFi command responses and sensor status JSON keys.
• Extend DHT11 sensor reporting with dew point, comfort, and condensation risk (including MQTT channel expansion).
• Add optional reboot-on-save behavior and fix a timezone wrap issue in sun time calculations.
