feat: "ARIA hart neu starten"-Button (docker restart aria-core)

Zweiter Eskalations-Button neben dem Reparieren-Button — fuer Faelle
wo doctor --fix nicht reicht (Run alive aber haengt im Tool-Call).
Mit Confirmation-Dialog damit's nicht versehentlich gedrueckt wird.

Wege:
- App-Settings: Reparatur-Sektion, zwei Buttons (Reparieren + Hart neu)
- App-Thinking-Bubble: 🔧 + 🚨 + Abbrechen
- Diagnostic-Thinking-Indicator: 🔧 + 🚨 + Abbrechen
- Diagnostic-Server: POST /api/aria-restart → child_process exec
  `docker restart aria-core`
- Bridge: rvs aria_restart → HTTP zu Diagnostic
