Separate my circles from visible circles I’m not part of

Describe the bug

Currently if a Nextcloud has many open ("visible to all" / "request membership") circles, they burry the circles a user is actually part of. It should be recognizable if I’m a member of a circle or if they are only shown to me.

I propose to at least move circles with membership to the top of the list. Additionally there could be additional separation by a horizontal line between my circles and open circles, a highlighted counter bubble or similar visual indicators.

Personally I would prefer to only list circles I‘m actually part of and provide a modal to "Browse open circles…". Maybe as a search icon next to the "+".

To Reproduce
Steps to reproduce the behavior:

1. Add several circles (maybe 20+) which are "Visible to all" to your Nextcloud.
2. Switch to another account wich already is in some circles and open Contacts.
3. Try to find your circles somewhere in a long list and try to recognize wich circles you are actually part of.

Expected behavior
A user should be able to cleary identify circles he is part of.

Actual behavior
A users circles are mixed with all the open/visible circles of the instance.

Server configuration

Nextcloud version: 22.1.1
Contacts version: 4.0.2
Circles version: 22.1.1

The issue does not name files, tests, or entry points. Reproduce the long-circle-list scenario in Contacts with open circles and an account that belongs to some circles, then inspect the circle-list UI and existing membership indicators. Done means a user can clearly distinguish circles they belong to from visible open circles, after the desired presentation is chosen.
