+.SYNOPSIS
+  Restore ODBC DSNs and registry keys, and identify missing drivers.
+
+.DESCRIPTION
+  - Extracts ODBC_Backup.zip into C:\ODBC_Migration\restore
+  - Imports all .reg and .xml files
+  - Recreates DSNs
+  - Compares exported vs installed ODBC drivers
+  - Displays missing drivers with official vendor download links
+  - Logs all operations
