GE-Enforce polish: DDL-parity guard test, retire Collector PC Types page

Add test_geenforce_ddl_parity to lock the manifest models against their
Alembic baseline (catches model/migration drift for a chain that is still
amendable pre-deploy).

Retire the "Collector PC Types" settings card: GE-Enforce scope
computertypeid supersedes the pctypemap editor UI (ADR-012). The collector
still reads pctype_mapping(), so the backend map stays; only the editor
surface is removed, with a deprecation note in pctypemap.py.
