Bugfixes & LittleFS Conversion

This release incorporates a handful of bugfixes for various issues found in alpha3:

• Reinitializes the display when toggling relays on via pins
• Adjusts Bluetooth scan time to reset more frequently
• Adjusts Inkbird timeout to 62 seconds to prevent erroneous disconnects
• Converts the ESP32 from SPIFFS to LittleFS

This alpha release does not include the S2 firmware, as further testing of the Filesystem conversion is required.
