Style events from invites differently if they need my action

[ChristophWurst]

Is your feature request related to a problem? Please describe.

As a Nextcloud user I have my own events and I get invited to meetings. When I open up my calendar I see all the meetings in my calendar already, because the backend copies them there. However, I might forget to actually respond to the invite, leaving the organizer hanging.

Describe the solution you'd like

Show events visually different when the attendee status is NEEDS-ACTION for me. Once I accept or decline, the event will change to "normal" appearance.

Google shows these events with stripes.

Describe alternatives you've considered

Sounds good to me and seems like a possible quick win and closing the gap of expectation. :)
