display sync_code on settings page
according to documentation https://docs.turris.cz/basics/apps/netmetr/#collected-data
Netmetr server stores your measurements linked to the device so that you can view all the past measurements on its website. To view your results you have to enter Sync code which is displayed in Netmetr Foris tab.
All the data are - after proper anonymization - also shared on Netmetr map and as an open data.
Altough the sync_code
is sent from backend, it's not visbile on router UI http://turris/reforis/netmetr/settings
