Recheck Boxine status on cloud.enabled change

[henryk86]

If the cloud.enabled setting is changed, update the boxine status.

Currently you have to reload the page completely.

a) add a periodically check (once every minute?)
b) refetch the status if setting is changed

[SciLor]

a) would add stress to the Boxine server.
b) (check)

c) Also do it, if certificates were changed, especially if you just added a new toniebox and this is the first certificate

[henryk86]

a) is not implemented
b) if cloud.enabled is changed - is implemented
c) if certificates are uploaded (settingswise) - is implemented
d) NEW if certs extracted automatically in ESP32 flashing process - is implemented

After Enabling cloud access sometimes update working boxine fails and boxine status stay red even if it is reachable. Recheck.
