Switch to ARIS external service of type DB

From version 10.0.12, the connection to the external database management system (DBMS) is standardized for all ARIS products. After migration, ARIS Risk & Compliance Manager still uses the old external service of type DB_ARCM. To simplify future updates and maintenance, it is recommended to switch to the central external service of type DB, which is used by all ARIS applications.
