Remove the fragile and heavy json libraries from the firmware, remove JSON topics on MQTT, remove JSON Logging/Tracing, replace JSON output on webserver with simple string concatenation, since they use a fixed set of templates anyway.

The Heltec solar node still uses ArduinoJSON for god knows what in its included custom library.
