[Feature]: Better overview of many locations

### Problem description

If having many locations in one instance in the client, we need to search for the right location and we don't see connected locations instantly.
Also, when upgrading the instance, we need to disconnect from all locations at once, best option is to close the client and stop the service.

### Proposed solution

Add a "List View" to the client, with a colored name field, to identify connected locations directly.
Add a "Disconnect All" button per instance.

### Alternatives considered

reducing grid view location box size

### Impact

Nice to have
