fix(escalations): add sidebar badge count + show all team escalations

- Add escalation_count to sidebar stats (team-wide requesting_escalation)
- Show badge on Escalations nav item in sidebar
- Remove user_id filter from escalation queue — show all team escalations
  including your own (needed for solo users and visibility)
