-/**
- * EmailTemplate Bridge – Schema-API für Quellsysteme.
- *
- * Diese Datei kann auf einer geschützten Quelle (z.B. Kundenserver) installiert werden.
- * Sie liefert dem EmailTemplate-System Informationen über verfügbare Tabellen/Spalten,
- * ohne direkten DB-Zugriff von außen zu erlauben.
- *
- * Sicherheit:
- *  - Authentifizierung per statischem Token (per Header oder Query-Parameter).
- *  - Optional können Host/IP-Checks ergänzt werden.
- *
- * Aktionen:
- *  - action=schema (Default)  → Gibt Tabellen inkl. Spaltendefinition zurück.
- *  - action=ping              → Kleiner Health-Check.
- *
- * Hinweise:
- *  - DB-Daten können direkt unten eingetragen oder aus einer separaten Datei geladen werden.
- *  - Der Token sollte für jede Installation eindeutig sein.
