Login sessions management

[janbarasek]

Implement custom logic for session management. Use existing table to store history.

In the account detail view:

• List of actively logged sessions that have not been marked as logged out.
• Ability to see which sessions are currently online (including propagating status to other application layers)
• A button to log out all sessions other than the acoustic one
• Button to log out all sessions, including the current one
• Automatic logout of all sessions if the user is locked out

Sessions must be authenticated in keep-auth requests. If the session is no longer valid, automatically log the user out.

Allow administrators to log out sessions of all other users (security).
