feat(session): centralize session teardown and refresh

Add SessionLifecycleService to reset user-scoped cubits, analytics, socket id and account-scoped preferences on logout, 401 or account deletion. Run the same refresh after every successful auth path, including registration v1/v2, and ignore 401 responses from stale tokens so an old request cannot terminate the new user's session.
