CDS view entity review card

• New models use define view entity; layer them basic (I_), composite or base (R_), consumption (C_).
• Build on released SAP views (check API State), not on SAP tables.
• Prefer associations with a leading underscore and an explicit cardinality; check them with Follow Association in Data Preview.
• Every amount and quantity has its currency or unit reference.
• UI annotations live in a metadata extension; the view sets @Metadata.allowExtensions: true.
• Business data views have a CDS role; consuming views get their own role or an inheritance condition.
• Review every #NOT_ALLOWED and WITH PRIVILEGED ACCESS.
• Test access with users who see all, some and nothing.
• Unit-test calculations and aggregations with the CDS test double framework.
