Update PMDB.Wbs formatted names and Udf values in Pivot.sql

[Imran-imtiaz48]

Optimizations: ✅ Better Recursive CTE Processing: Avoid unnecessary joins in wbs_relate. ✅ Using FORMAT for Dates: Improves readability and avoids unnecessary conversions. ✅ Using NVARCHAR Where Needed: Prevents implicit conversion issues. ✅ Filtering Before Pivoting: Reduces data volume before applying PIVOT. ✅ Avoiding SELECT *: Explicitly selecting required columns for better performance. ✅ Removing Redundant 1=1 Conditions: These are unnecessary and don’t impact execution.
