Refactor backend CORS settings to include default origins and improve error handling in chat services: Introduce dynamic CORS origin handling, enhance RabbitMQ message sending with fallback mechanisms, and update WebSocket service to manage pending messages. Update UI components for better accessibility and responsiveness, including adjustments to dialog and navigation elements. Enhance styling for improved user experience across various components.

This reverts commit 8c40144734.

+# Church Models - Übersicht für Daemon-Entwicklung
+
+## 1. ChurchOfficeType (falukant_type.church_office_type)
+
+**Schema:** `falukant_type`  
+**Tabelle:** `church_office_type`  
+**Zweck:** Definiert die verschiedenen Kirchenämter-Typen
+
+```javascript
+{
+  id: INTEGER (PK, auto-increment)
+  name: STRING (z.B. "pope", "cardinal", "lay-preacher")
+  seatsPerRegion: INTEGER (Anzahl verfügbarer Plätze pro Region)
+  regionType: STRING (z.B. "country", "duchy", "city")
+  hierarchyLevel: INTEGER (0-8, höhere Zahl = höhere Position)
+}
+```
+
+**Beziehungen:**
+- `hasMany` ChurchOffice (als `offices`)
+- `hasMany` ChurchApplication (als `applications`)
+- `hasMany` ChurchOfficeRequirement (als `requirements`)
+
+---
+
+## 2. ChurchOfficeRequirement (falukant_predefine.church_office_requirement)
+
+**Schema:** `falukant_predefine`  
+**Tabelle:** `church_office_requirement`  
+**Zweck:** Definiert Voraussetzungen für Kirchenämter
+
+```javascript
+{
+  id: INTEGER (PK, auto-increment)
+  officeTypeId: INTEGER (FK -> ChurchOfficeType.id)
+  prerequisiteOfficeTypeId: INTEGER (FK -> ChurchOfficeType.id, nullable)
+  minTitleLevel: INTEGER (nullable, optional)
+}
+```
+
+**Beziehungen:**
+- `belongsTo` ChurchOfficeType (als `officeType`)
+- `belongsTo` ChurchOfficeType (als `prerequisiteOfficeType`)
+
+---
+
+## 3. ChurchOffice (falukant_data.church_office)
+
+**Schema:** `falukant_data`  
+**Tabelle:** `church_office`  
+**Zweck:** Speichert tatsächlich besetzte Kirchenämter
+
+```javascript
+{
+  id: INTEGER (PK, auto-increment)
+  officeTypeId: INTEGER (FK -> ChurchOfficeType.id)
+  characterId: INTEGER (FK -> FalukantCharacter.id)
+  regionId: INTEGER (FK -> RegionData.id)
+  supervisorId: INTEGER (FK -> FalukantCharacter.id, nullable)
+  createdAt: DATE
+  updatedAt: DATE
+}
+```
+
+**Beziehungen:**
+- `belongsTo` ChurchOfficeType (als `type`)
+- `belongsTo` FalukantCharacter (als `holder`)
+- `belongsTo` FalukantCharacter (als `supervisor`)
+- `belongsTo` RegionData (als `region`)
+
+---
+
+## 4. ChurchApplication (falukant_data.church_application)
+
+**Schema:** `falukant_data`  
+**Tabelle:** `church_application`  
+**Zweck:** Speichert Bewerbungen für Kirchenämter
+
+```javascript
+{
+  id: INTEGER (PK, auto-increment)
+  officeTypeId: INTEGER (FK -> ChurchOfficeType.id)
+  characterId: INTEGER (FK -> FalukantCharacter.id)
+  regionId: INTEGER (FK -> RegionData.id)
+  supervisorId: INTEGER (FK -> FalukantCharacter.id)
+  status: ENUM('pending', 'approved', 'rejected')
+  decisionDate: DATE (nullable)
+  createdAt: DATE
+  updatedAt: DATE
+}
+```
+
+**Beziehungen:**
+- `belongsTo` ChurchOfficeType (als `officeType`)
+- `belongsTo` FalukantCharacter (als `applicant`)
+- `belongsTo` FalukantCharacter (als `supervisor`)
+- `belongsTo` RegionData (als `region`)
+
+---
+
+## Zusätzlich benötigte Models (für Daemon)
+
+### RegionData (falukant_data.region)
+- Wird für `regionId` in ChurchOffice und ChurchApplication benötigt
+- Enthält `regionType` (country, duchy, markgravate, shire, county, city)
+- Enthält `parentId` für Hierarchie
+
+### FalukantCharacter (falukant_data.character)
+- Wird für `characterId` (Inhaber/Bewerber) benötigt
+- Wird für `supervisorId` benötigt
+
+---
+
+## Wichtige Queries für Daemon
+
+### Verfügbare Positionen finden
+```sql
+SELECT cot.*, COUNT(co.id) as occupied_seats
+FROM falukant_type.church_office_type cot
+LEFT JOIN falukant_data.church_office co 
+  ON cot.id = co.office_type_id 
+  AND co.region_id = ?
+WHERE cot.region_type = ?
+GROUP BY cot.id
+HAVING COUNT(co.id) < cot.seats_per_region
+```
+
+### Supervisor finden
+```sql
+SELECT co.* 
+FROM falukant_data.church_office co
+JOIN falukant_type.church_office_type cot ON co.office_type_id = cot.id
+WHERE co.region_id = ?

+    SELECT hierarchy_level 
+    FROM falukant_type.church_office_type 
+    WHERE id = ?
+  )
+ORDER BY cot.hierarchy_level ASC
+LIMIT 1
+```
+
+### Voraussetzungen prüfen
+```sql
+SELECT cor.*
+FROM falukant_predefine.church_office_requirement cor
+WHERE cor.office_type_id = ?
+```
+
+### Bewerbungen für Supervisor
+```sql
+SELECT ca.*
+FROM falukant_data.church_application ca
+WHERE ca.supervisor_id = ?
+  AND ca.status = 'pending'

+# SSL/TLS Setup für YourPart Daemon
+
+Dieses Dokument beschreibt, wie Sie SSL/TLS-Zertifikate für den YourPart Daemon einrichten können.
+
+## 🚀 Schnellstart
+
+### 1. Self-Signed Certificate (Entwicklung/Testing)
+```bash
+./setup-ssl.sh
+# Wählen Sie Option 1
+```
+
+### 2. Let's Encrypt Certificate (Produktion)
+```bash
+./setup-ssl.sh
+# Wählen Sie Option 2
+```
+
+### 3. Apache2-Zertifikate verwenden (empfohlen für Ubuntu)
+```bash
+./setup-ssl.sh
+# Wählen Sie Option 4
+# Verwendet bereits vorhandene Apache2-Zertifikate
+# ⚠️ Warnung bei Snakeoil-Zertifikaten (nur für localhost)
+```
+
+### 4. DNS-01 Challenge (für komplexe Setups)
+```bash
+./setup-ssl-dns.sh
+# Für Cloudflare, Route53, etc.
+```
+
+## 📋 Voraussetzungen
+
+### Für Apache2-Zertifikate:
+- Apache2 installiert oder Zertifikate in Standard-Pfaden
+- Unterstützte Pfade (priorisiert nach Qualität):
+  - `/etc/letsencrypt/live/your-part.de/fullchain.pem` (Let's Encrypt - empfohlen)
+  - `/etc/letsencrypt/live/$(hostname)/fullchain.pem` (Let's Encrypt)
+  - `/etc/apache2/ssl/apache.crt` (Custom Apache2)
+  - `/etc/ssl/certs/ssl-cert-snakeoil.pem` (Ubuntu Standard - nur localhost)
+
+### Für Let's Encrypt (HTTP-01 Challenge):
+- Port 80 muss verfügbar sein
+- Domain `your-part.de` muss auf den Server zeigen
+- Kein anderer Service auf Port 80
+
+### Für DNS-01 Challenge:
+- DNS-Provider Account (Cloudflare, Route53, etc.)
+- API-Credentials für DNS-Management
+
+## 🔧 Konfiguration
+
+Nach der Zertifikats-Erstellung:
+
+1. **SSL in der Konfiguration aktivieren:**
+   ```ini
+   # /etc/yourpart/daemon.conf
+   WEBSOCKET_SSL_ENABLED=true
+   WEBSOCKET_SSL_CERT_PATH=/etc/yourpart/server.crt
+   WEBSOCKET_SSL_KEY_PATH=/etc/yourpart/server.key
+   ```
+
+2. **Daemon neu starten:**
+   ```bash
+   sudo systemctl restart yourpart-daemon
+   ```
+
+3. **Verbindung testen:**
+   ```bash
+   # WebSocket Secure
+   wss://your-part.de:4551
+   
+   # Oder ohne SSL
+   ws://your-part.de:4551
+   ```
+
+## 🔄 Automatische Erneuerung
+
+### Let's Encrypt-Zertifikate:
+- **Cron Job:** Täglich um 2:30 Uhr
+- **Script:** `/etc/yourpart/renew-ssl.sh`
+- **Log:** `/var/log/yourpart/ssl-renewal.log`
+
+### Apache2-Zertifikate:
+- **Ubuntu Snakeoil:** Automatisch von Apache2 verwaltet
+- **Let's Encrypt:** Automatische Erneuerung wenn erkannt
+- **Custom:** Manuelle Verwaltung erforderlich
+
+## 📁 Dateistruktur
+
+```
+/etc/yourpart/
+├── server.crt          # Zertifikat (Symlink zu Let's Encrypt)
+├── server.key          # Private Key (Symlink zu Let's Encrypt)
+├── renew-ssl.sh        # Auto-Renewal Script
+└── cloudflare.ini      # Cloudflare Credentials (falls verwendet)

+├── cert.pem            # Zertifikat
+└── chain.pem           # Intermediate Certificate
+```
+
+## 🛠️ Troubleshooting
+
+### Zertifikat wird nicht akzeptiert
+```bash
+# Prüfe Zertifikats-Gültigkeit
+openssl x509 -in /etc/yourpart/server.crt -text -noout
+
+# Prüfe Berechtigungen
+ls -la /etc/yourpart/server.*
+```
+
+### Let's Encrypt Challenge fehlgeschlagen
+```bash
+# Prüfe Port 80
+sudo netstat -tlnp | grep :80
+
+# Prüfe DNS
+nslookup your-part.de
+
+# Prüfe Firewall
+sudo ufw status
+```
+
+### Auto-Renewal funktioniert nicht
+```bash
+# Prüfe Cron Jobs
+sudo crontab -l
+
+# Teste Renewal Script
+sudo /etc/yourpart/renew-ssl.sh
+
+# Prüfe Logs
+tail -f /var/log/yourpart/ssl-renewal.log
+```
+
+## 🔒 Sicherheit
+
+### Berechtigungen
+- **Zertifikat:** `644` (readable by all, writable by owner)
+- **Private Key:** `600` (readable/writable by owner only)
+- **Owner:** `yourpart:yourpart`
+
+### Firewall
+```bash
+# Öffne Port 80 für Let's Encrypt Challenge
+sudo ufw allow 80/tcp
+
+# Öffne Port 4551 für WebSocket
+sudo ufw allow 4551/tcp
+```
+

+- [libwebsockets SSL](https://libwebsockets.org/lws-api-doc-master/html/group__ssl.html)
+
+## 🆘 Support
+
+Bei Problemen:
+1. Prüfen Sie die Logs: `sudo journalctl -u yourpart-daemon -f`
+2. Testen Sie die Zertifikate: `openssl s_client -connect your-part.de:4551`
+3. Prüfen Sie die Firewall: `sudo ufw status`
