[FEATURE]: match formatting of calendar & agenda events, and make calendar events optional

[ounrequitedo]

Is your feature request related to a problem? Please describe.
when adding the calendar and agenda modules, you can easily see the difference in formatting of the two modules, which are kind of redundant in function

Describe the solution you'd like
please remove agenda items section from the calendar module or make them optional with a toggle, as it's already served by the exclusive agenda module anyways and the formatting of both do not match (the agenda module is nicer and easier to read too imo)

Describe alternatives you've considered
in the meantime, working directly with @aceisace i've hidden the events section of the Calendar app by changing the code in the calendar modules, but it may not persist through upgrades

Additional context
thanks for the discord help!
