ci: decouple production deploy from smoke gate

continue-on-error is not supported on reusable workflow (uses:) job calls —
the workflow was failing at setup with no jobs spawned.

Fix: remove smoke from deploy-production needs. Smoke tests still run in
parallel (for visibility) but production no longer waits on them. Re-add
smoke to needs once peptide-e2e suite is stable and exercising staging.
