Move projection logic off wire classes into adapter-side translator modules

[sei-ahouseholder]

Summary

Move projection logic off the wire vocabulary classes into translator modules on
the adapter side. This is the change that makes ARCH-22 achievable rather than
merely redefined — wire classes end up as pure AS2 shape with no domain knowledge.

354 lines of to_core/from_core/_to_core_data are spread across 13 wire files.
After the generic-translator task most of it is already gone; this task relocates
what remains, including the three structural projections
(as_VulnerabilityCase, as_CaseStatus, as_CaseParticipant).

Acceptance Criteria

• AC-1: No from_core() or to_core() method remains on any wire vocabulary
  class; translation lives in adapter-side translator modules (ARCH-12-005 as
  amended by ADR-0081).
• AC-2: These 11 files no longer import vultron.core.models: case_actor,
  case_ledger_entry, case_participant, case_reference, case_status,
  embargo_event, embargo_policy, vulnerability_case,
  vulnerability_record, vulnerability_report, vultron_actor
  (all under vultron/wire/as2/vocab/objects/).
• AC-3: vultron/wire/as2/vocab/activities/base.py, activities/actor.py,
  activities/case.py, factories/actor.py and factories/case.py are
  triaged: each either clears its import or is added to the declared exemption
  set with the requirement that mandates it.
• AC-4: Nested-child projection still recurses correctly. as_VulnerabilityCase
  projects case_participants, case_statuses and active_embargo;
  as_CaseParticipant projects participant_statuses. Round-trip tests cover
  each nesting level.
• AC-5: Serialized AS2 output is byte-identical to pre-change output
  (ARCH-23-003).
• AC-6: KNOWN_VIOLATIONS shrinks by the entries cleared.
• AC-7: Full unit suite and integration suite both pass.

Prior Art

• vultron/adapters/driven/wire_render/as2.py — the existing adapter-side
  translation entry point; extend rather than duplicate.
• vultron/adapters/driven/trigger_activity_adapter/_base.py:61-76 — already calls
  wire_cls.from_core(core_obj) from the adapter side; a natural consumer.
