+# Service to convert legacy WhatsApp template parameter formats to enhanced format
+#
+# Legacy formats (deprecated):
+# - Array: ["John", "Order123"] - positional parameters
+# - Flat Hash: {"1": "John", "2": "Order123"} - direct key-value mapping
+#
+# Enhanced format:
+# - Component-based: {"body": {"1": "John", "2": "Order123"}} - structured by template components
+# - Supports header, body, footer, and button parameters separately
