feat: "ARIA reparieren"-Button in App + Diagnostic

Bei stuck OpenClaw-Runs (ARIA antwortet nicht mehr / "Antwort ohne Text"
auf jede Anfrage) kann der User jetzt selbst openclaw doctor --fix
anstossen — ohne SSH/docker exec.

Pfad:
- App-Button → rvs.send('doctor_fix') → Bridge → HTTP POST an
  Diagnostic /api/doctor-fix → dockerExec aria-core
- Diagnostic-Button → direkt HTTP POST /api/doctor-fix

Zwei Plaetze in der App: oben in der Thinking-Bubble (wenn ARIA denkt
aber haengt) und in Settings → Reparatur (immer erreichbar). In
Diagnostic neben dem Abbrechen-Button im Thinking-Indicator.
