chore: devops compose tweaks, playwright artifacts, sprint log updates

devops/compose: docker-compose.stella-ops.legacy.yml +
docker-compose.stella-services.yml receive small service wiring updates.

Playwright: refreshed auth-state/report fixtures from the latest
integrations + setup-wizard + policy-runtime live runs. Includes a new
playwright-report-integrations/ bundle.

Docs: SPRINT_20260410_001 (runtime no-mocks) significantly expanded with
additional NOMOCK tasks reflecting the Postgres-backed work shipped across
Policy, Graph, Excititor, VexLens, Scanner, VexHub. SPRINT_20260413_004
(UI-only setup bootstrap closure) log updates.

Gitignore: narrow the earlier `output/` rule to `/output/` so the tracked
src/Web/StellaOps.Web/output/playwright fixtures continue to be picked up.
