feat: Phase 1 — agent status toggle, global search, enquiry form

- Agent status toggle: Ready/Break/Training/Offline with Ozonetel sync
- Global search: cross-entity search (leads + patients + appointments) via sidecar
- General enquiry form: capture caller questions during calls
- Button standard: icon-only for toggles, text+icon for primary actions
- Sidecar: agent-state endpoint, search module with platform queries
