feat(cutover): platform services build from ../mana, not from this repo

Part of the 8-Doppel-Cutover (2026-05-08, plan
~/.claude/plans/floating-swinging-flurry.md):

- docker-compose.{macmini,dev,test}.yml: build context for
  mana-{auth,credits,media,llm,notify} switched to ../mana/services/...
  so the Mac Mini stack pulls platform services from the platform repo
  (sibling clone), not from services/ in this monorepo.
- .npmrc + apps/api/{Dockerfile,package.json}: @mana/media-client now
  resolved from Verdaccio (npm.mana.how, ^0.1.0) instead of as a
  workspace COPY from services/mana-media/packages/client. Build-arg
  NPM_TOKEN flows through .npmrc for pnpm install auth. Required
  before services/mana-media/ can be deleted.
- .github/workflows/{ci,cd-macmini,daily-tests}.yml: removed the
  detect-/build-/test-jobs that targeted services/mana-{auth,credits,
  notify,media}/. Those services build out of the platform repo now —
  CI for them belongs in mana/-repo (open). cd-macmini's
  workflow_dispatch can still rebuild any of them on demand;
  auto-detect on path-change is gone for these five.
- scripts/{mac-mini/push-schemas.sh,run-integration-tests.sh}:
  rewritten to look in ../mana/ for the platform services.
- package.json dev:{auth,credits,notify,media}: paths point at
  ../mana/services/... so local dev still works post-cutover.

What this commit does NOT do: delete services/mana-{auth,credits,...}
from this repo. That waits for Phase 7 once the Mac Mini stack has
booted cleanly from the new build paths.
