Performance improvement - faster event definition loading with selectize dropdown

In previous versions, when a large number of ResourceTypes (tested with 100 000) resulted in the generation of numerous shadow Data Object Types, opening Event Definitions could take several minutes.

In this release, we have addressed this issue by implementing a selectize box for the Triggering DataObjectType dropdown on Event Definitions. This enhancement significantly improves performance, especially in cases with tens of thousands of DataObjectTypes.
