feat(ucca): adopt obligation_id + harden join to semantic (step 3 core)

The Obligation Registry filled proposed_obligation_id (7/7) + cut the logging
family (obligations 47->66). Adopted obligation_id onto our 7 accepted CRA->OWASP
mappings; the join now prefers the EXACT obligation_id over the coarse
citation_unit (which stays as fallback for not-yet-adopted rows).

Effect: semantic coverage 2->4 (user_authentication_required,
credential_confidentiality_protection, auth_key_management,
event_logging_security_events). Befund 1 resolved: V11.2.1 crypto now sits under
credential_confidentiality_protection, not user_authentication_required.
