postgsail/initdb/99_migrations_202407.sql
xbgmsharp 0a13e0a798 Add migration 202407 
- Add video error notification message
- Add CRON for new video notification
- Update public.cron_alerts_fn, Fix error when stateOfCharge is null. Make stateOfCharge null value assume to be charge 1.
- Update api.export_logbooks_gpx_fn, Fix error: None of these media types are available: text/xml
- Add export logbooks as png from webserver
- Update grafana provisioning, ERROR:  KeyError: 'secureJsonFields'
- Add missing comment on function cron_process_no_activity_fn
- Update grafana role SQL connection to 30
- Create qgis schema for qgis projects
- Update video cronjob
