fix(ci): preserve staging dashboard domain during deployment

Omit staging route declarations and disable workers.dev so Wrangler preserves the existing qa-test custom domain without requesting zone routing access. Match the production domain management model.

Validation: 123 tests and a real Wrangler dry-run pass. New staging organization key passes org:verify; run 227269 attempt 2 then failed on the zone workers/routes API before this configuration fix.
