[HOLD for payment 2024-11-05] [HIGH] [Attendee Tracking] Create Attendees item row for requests

[Julesssss]

Create the Attendee request row item that opens the AttendeeSelectionPage and displays the currently selected attendees.

Requirements
- Should be displayed conditionally during creation under the extra fields
- Opens AttendeeSelectionPage when tapped
- Update policy violation limit for multiple participants and highlight per-person amount (we can split this into a separate issue if that's preferred)

More details here, here and other places in the design document.

Hey @zfurtak @filip-solecki, it would be great if you could make a start on this issue. I'm around for any questions and we'll be focusing on the backend issue for persisting and passing the attendee Onyx data back to the client.

I believe you should be able to workaround that in the meantime 🤞

Feel free to further break down these tasks, and we can merge these to a branch like this until the backend issues are completed feature-attendeeTracking. Let me know if you have any further questions.

Will be picked up soon
