fulfillr-dev: staging back-office container + Turso store prep

Add a second go-fulfillr container (fulfillr-dev) wired to the staging
Turso store + EasyPost/Stripe test keys via dev.json, served at
fulfillr-dev.debyltech.com (Caddy -> :9055), LAN-restricted like prod.

- fulfillr-dev.yml + dev.json.j2: the staging container, volumes, config
- defaults: fulfillr_dev_* vars; prod store URL stubbed off until cutover
- Caddyfile + caddy.yml: fulfillr-dev site block and static mount
- awsddns.yml: Route53 DDNS for the fulfillr-dev hostname
- production.json.j2: add store_database_url/store_auth, rename stripe key
  var to fulfillr_stripe_api_key
- vault.yml: dev + store/stripe secrets
