Bugfix and QOL update

- Added watchdog to ensure 1.5 minutes evaluation of temperatur
- added boot time output to MQTT ti track reboots
- keep chosen set temp during resets (only power loss will result in reading the default temp from flash)
- Add smaller case to fit concrete wall housings
- added command to upload firmware to all targets as comment in platformio.ini
