feat: use CF Service Bindings for logic components (no public network)

- Add 15 [[services]] bindings in cypher-executor wrangler.toml
- component-loader now calls logic Workers via Service Binding (svc.fetch)
  instead of public URL fetch (which caused 522 timeout within same zone)
- Fallback to public URL if binding not available (dev/testing)
- Add ServiceBinding type to Bindings
