Entities HAL-01

[gRoussac]

Updated get_immediate_caller and Add key_as_account_or_package Key conversion

maintains CEP-18 compatibility, and standardizes caller Key for balances and allowances dictionaries.

• Updated get_immediate_caller to clearly map different caller kinds (ACCOUNT, CONTRACT, ENTITY) to a Key, handling:

  Legacy accounts + New entities account → AccountHash

  Legacy contract packages → ContractPackageHash

  New entities (not account)→ PackageHash

• Introduced key_as_account_or_package helper to convert new-style Key returned by get_immediate_caller into a compatible Key (AccountHash / Hash), ensuring backward compatibility. Storage keeps Key (AccountHash / Hash).

• Documented behavior

• Testing note: In tests enabling Addressable entities in test builder is depending on added feature test-enable-addressable-entity . Test are now run with or without addressable-entity
