feat: OpenAI Provider, Key-Checker Quota-Erkennung, persistierte Scanner-Logs

- OpenAI als vollwertiger Chat-Provider (Modell-Auswahl, Key-Routing, StreamChat)
- Hardcoded OpenAI-Modelle im Cache (gpt-5.x, gpt-4.1, o3, o4-mini etc.)
- /api/models/openai Endpoint, OpenAI-Optgroup im Agent-Dropdown
- Key-Routing: OpenAI-Key aus api_keys-Tabelle, Fallback via GetFirstActiveKeyByProvider
- OpenAI-Checker: 2-Schritt-Check (Models + chat/completions mit max_tokens=1)
- Google-Checker: 2-Schritt-Check (Models + generateContent mit maxOutputTokens=1)
- 429 insufficient_quota und billing_not_active korrekt als quota_exceeded erkannt
- Provider-Erkennung beim Adopt via KeyPatterns.DetectType() statt hardcoded anthropic
- HandleCheck/HandleCheckAll unterstützt jetzt Anthropic, OpenAI und Google
- Neue scanner_logs-Tabelle mit details-Spalte (JSON) für strukturierte Auswertung
- GitHubEventScannerService: AddLog persistiert in DB, detaillierte Key-Fund-Logs
- KeyScannerService: AddLog-Methode mit DB-Persistierung, detaillierte Logs
- Frontend: Ungeprüfte-prüfen-Button (sequenziell, stoppt bei valid)
- Frontend: Provider-Indicator im Key-Switch-Modal (Anthropic/OpenAI/Google)
- Frontend: Check-Button für alle Provider (nicht nur Anthropic)
