fix(diagnostic): chat_history-Render verträgt kaputte Bubbles + EHOSTUNREACH skipped TLS-Fallback

Browse Source 
Zwei kleine Robustness-Verbesserungen:

1) chat_history-Handler im Frontend: jede Bubble jetzt in try/catch. Wenn
   eine Bubble bei der Render-Pipeline (escape/linkify/regex-replace) eine
   Exception wirft, brach die ganze for-Schleife ab und alle nachfolgenden
   Bubbles wurden nicht mehr in den DOM geschrieben — beim Reload sah man
   dann nur die ersten N Eintraege und Stefan dachte die letzten Antworten
   waeren weg. Jetzt: Fehler-Bubble mit "⚠ Render-Fehler" + console.error,
   restliche Bubbles laufen weiter durch.

2) Diagnostic-Server RVS-Reconnect: TLS-Fallback war auch bei reinen
   Netz-Fehlern (EHOSTUNREACH, ECONNREFUSED, ENETUNREACH, ETIMEDOUT,
   ENOTFOUND, EAI_AGAIN) gefeuert — bringt nichts weil der Server eh tot
   ist, generiert aber doppelte Reconnect-Versuche + Log-Spam. Jetzt nur
   noch bei wirklichen TLS/Handshake-Fehlern.
