Default calendar editing mode when new user created

Is your feature request related to a problem? Please describe.
Relates to issue #2960 where a jump to calendar from dashboard using chrome based browser will go unresponsive. From testing done on NC23.0.0 - a new user seems to be created with simplified editing disabled and will therefore hang when using the dashboard

This may or may not be down to chrome bugs but it is not a good user experience for non technical users as asking them change settings should not be necessary

Describe the solution you'd like
When an admin creates a new user:
==> create the users calendar with a default of simplified not set
OR
==> inherit the admin's current settings

Describe alternatives you've considered
allow default calendar settings to be set using the occ config:app:set capability
I'm happy to do this but do not know a). if this setting is exposed to occ and b). if so, what it's called

No files or tests are named. Start by tracing how a newly created user's calendar editing preference is initialized and how the simplified editing setting is read when opening the calendar from the dashboard. Done means new users receive the intended default or inherited setting without manual configuration, and the dashboard calendar remains responsive.
