Add GE-Enforce observed-state reporting: receipt + self-heal from PCs

PCs now report enforcement results back to shopdb, closing the desired-vs-observed
loop.

- POST /api/geenforce/report (geenforce.report service token): each cycle a PC
  posts the published version it applied, install/skip/fail/filtered counts, and
  per-entry outcomes.
- Two tables: manifestenforcementreports (latest-per-host + history: applied
  version, enforcer version, counts, derived status ok/selfhealed/failed) and
  manifestenforcementresults (per entry: action installed/skipped/failed,
  selfhealed flag, exit code, warning/error message).
- RECEIVED: reports carry the applied version; the admin view derives
  receivedlatest by comparing it to the scope's current published version, so
  the fleet view shows which PCs picked up an update.
- SELF-HEAL: per-entry action captures drift correction (installed when it
  should already be present) vs skipped (already good) vs failed, with messages.
- Admin reads: GET /reports (fleet compliance rollup) and GET /reports/<id>
  (per-entry detail). New geenforce.report permission.
- Tables added to the (undeployed) 0001 baseline; geenforce.post_report is a
  service-token endpoint so it is exempt from the JWT authz sweep, like the
  collector blueprint. 8 reporting tests; full suite green.
