Persistence Panel (#22979)

# Summary

This PR adds a new admin panel for persistence.

## Contents

- The panel features information about the current round and detailed
tracking of objects, records and generics.
- The previously introduced toggle-persistence verb has been removed and
integrated into the new panel.
- The panel can be seen by admins, mods and devs, but the
toggle-persistence is still locked to admin permissions only.

## Preview

The images are WIP and subject to change.
