BigID DSPM Asset expanding and mapping

[mhebrard-bigid]

Change(s):

• Renamed column "case" to "dspmCase" in BigIDDSPMCatalog_CL table schema
• Renamed column "affectedObjects" to "expand" in BigIDDSPMCatalog_CL table schema
• using ASI/Microsoft/MvExpandTransformer to expand the column "expand" into several entries instead of a list. Result goes eventually to BigIDDSPMAssetStore_CL after DCR
• Added new table BigIDDSPMAssetStore_CL with comprehensive asset tracking schema including 25+ columns for asset metadata, permissions, classification, and risk information

Reason for Change(s):

• Improved column naming clarity to avoid conflicts with reserved keywords ("case")
• Enhanced data structure to support expanded BigID DSPM asset tracking capabilities
• Added comprehensive asset store schema to capture detailed asset information including ownership, permissions, classification, and risk data

Version Updated:

• N/A (Data Connector table schema changes, not a Detection/Analytic Rule template)

Testing Completed:

• Yes - Validated JSON schema structure for both table definitions
• Verified column types and descriptions are properly formatted
