Comparing to the previous patch (FAF2.6.3N_1926_COM-Q3-25 or FPatch1922) the following alterations have been made for Wuestenrot (for both TM and CRSM):
 - AgentContact_flag calculation has been altered (FA_CUSTOMERS.CustomerEMail and FA_CUSTOMERS.CustomerPhoneNumber are used instead of FA_CONTACTS.ContactValue)
 - AgentContact_days has been eliminated
Additionally, scoring_alerts got the same alterations which had been made in FPatch1922 for scoring (string_agg is used instead of standard XML-based text concatenation)
