HPKE missing from algorithmFamiliesEnum

[Mehrn0ush]

Describe the defect

HPKE is defined in schema/cryptography-defs.json but is missing from schema/cryptography-defs.schema.json#/definitions/algorithmFamiliesEnum. BOM 1.7 validates cryptoProperties.algorithmProperties.algorithmFamily against this enum, so using HPKE fails validation.

Additional context

Reproduction

1. Copy tools/src/test/resources/1.7/valid-cryptography-implementation-1.7.json.
2. Change cryptoProperties.algorithmProperties.algorithmFamily from AES to HPKE.
3. Validate against schema/bom-1.7.schema.json.

Observed error:

/components/0/cryptoProperties/algorithmProperties/algorithmFamily: 'HPKE' is not one of [...]

Expected

HPKE should be accepted as a valid algorithm family.

Proposed fix

Add "HPKE" to algorithmFamiliesEnum (alphabetically between GOST and HC).
