Design the syncing status

## Description

Research about which information we can use to show the replication status. Predict the `syncing status` for each identity displayed on the side panel and include a most complete feedback of this status on the profile page.

## Acceptance Criteria

- [ ] Research about which information we can use to show the rep status (credentials; apps; sessions and so on.)
- [ ] Add `syncing status` on the sidepanel
- [ ] Add `syncing status` on the profile page

Start by researching which credentials, apps, sessions, and other information can indicate replication status for each identity. Then examine the side panel and profile page entry points and define how the status should be presented in both places. Done means the available status data is identified and syncing status feedback is included on both views.
