docs: Phase 1 complete - Update documentation for social media consent system

✅ Phase 1 Complete (Nov 9-10, 2025):
- GDPR-compliant consent management fully implemented
- Mandatory workshop display consent + optional social media consents
- Consent badges, filtering, and CSV/JSON export in moderation panel
- Automatic migration system fixed (inline comments handling)
- GDPR compliance validated: 72 production groups with display_in_workshop = 0
- All features tested and production-ready

Documentation Updates:
- FEATURE_PLAN-social-media.md: All Phase 1 tasks marked complete
- README.md: Added consent system to features, updated database schema, new API endpoints
- README.dev.md: Complete developer guide with debugging, testing, and troubleshooting

Technical Achievements:
- 12 commits over 2 days (faster than 4-5 day estimate)
- Zero GDPR violations (retroactive consent fix validated)
- Zero breaking changes to existing functionality

Ready for Code Review and Production Deployment

-## 🔗 Abhängigkeiten
+## <20> Bekannte Issues & Fixes
+
+### Issue 1: Filter zeigte keine Bilder (9. Nov) - ✅ GELÖST
+**Problem**: `getGroupsByConsentStatus()` gab nur Metadaten ohne Bilder zurück  
+**Lösung**: Filter lädt ALLE Gruppen mit `getAllGroupsWithModerationInfo()`, dann In-Memory-Filterung
+
+### Issue 2: "Nur Werkstatt" Filter zeigte nichts (9. Nov) - ✅ GELÖST
+**Problem**: Filter prüfte `array.length === 0` statt `consent.consented === 1`  
+**Lösung**: Korrekte Boolean-Prüfung auf `consented` Feld
+
+### Issue 3: Alle Filter gaben 0 Gruppen zurück (9. Nov) - ✅ GELÖST
+**Problem**: `display_in_workshop` fehlte in `groupFormatter.formatGroupDetail()`  
+**Lösung**: Feld hinzugefügt in Commit f049c47
+
+### Issue 4: GDPR-Verletzung in Migration 005 (10. Nov) - ✅ GELÖST & VALIDIERT
+**Problem**: `UPDATE groups SET display_in_workshop = 1` setzte alle alten Gruppen auf "consented"  
+**Lösung**: UPDATE entfernt, alte Gruppen bleiben bei `display_in_workshop = 0` (expliziter Consent erforderlich)  
+**Test**: Mit 72 Produktionsgruppen validiert - alle haben display_in_workshop = 0 ✅
+
+### Issue 5: Automatisches Migrationssystem - inline Kommentare (10. Nov) - ✅ GELÖST
+**Problem**: SQL-Statements mit inline Kommentaren (z.B. `TEXT; -- comment`) wurden fehlerhaft geparst  
+**Lösung**: DatabaseManager entfernt jetzt alle Kommentare (Zeilen- und inline) vor dem Statement-Split  
+**Commit**: `8e62475` - "fix: DatabaseManager removes inline comments correctly in migrations"  
+**Test**: Migration 005 & 006 laufen jetzt automatisch beim Backend-Start ✅
