fix(caldav): show confidential event if writable
If a party can edit the calendar/event, just display it instead of hiding the details and risking overwrites. This might be considered a change impacting privacy, but it actually improves semantics. Relevant test updates included, improving assertion correctness. I think all the relevant use cases are solved by this.
