Add staging marketing site and Cloudflare Access gate

- Deploy marketing site to neuron-stage namespace (replaces bare REST catch-all)
- Staging uses test-mode Stripe keys from Vault
- Updated stage ingress to match prod routing pattern (MCP paths + marketing at /)
- Cloudflare Access: stage.neurontechnologies.ai requires Google auth
  - @neurontechnologies.ai domain allowed
  - 1timlingo@gmail.com explicitly allowed
