feat(crypto): support standardized algorithm identifiers

CycloneDX 1.7 distinguishes schema-defined families and curves while
older consumers still depend on free-form curve metadata.

Derive the accepted cases from the bundled schema and gate standardized
serialization to the new view. Preserve the legacy value through
comparison and rendering, then exercise strict schema output and
downgrade behavior.
