3.8.2

Bug fix
The most important changes in 3 points:

Error 403 (no image): Home Assistant was locking the screen. The solution is to remove the blocked IP from the ip_bans.yaml file.
Broken charts (rejected data): I corrected the code to correctly read sensor results with comma (e.g. 21,5 -> 21.5).
Bug Fixes: We removed the unnecessary send_exchange_rates service and added auto-installation of the missing graphics package in the background (matplotlib) for Raspberry Pi.
