[codex] Complete OMLOX REST endpoint coverage

[jillesvangurp]

Summary

• expand the normative OpenAPI contract with the missing OMLOX v2 REST routes
• implement provider, trackable, fence, zone summary, transform, collection, and nested resource behavior
• expose transient provider and trackable location/motion state through REST
• regenerate the Go server bindings and add route coverage

Why

Several OMLOX companion OpenAPI endpoints were absent from the repository contract and router, causing conforming requests such as PUT /v2/providers/{providerId}/location and GET /v2/zones/summary to return 404.

Validation

• just bootstrap
• just generate
• go test ./internal/hub ./internal/httpapi/handlers ./cmd/hub
• git diff --check

go test ./... passes for non-integration packages. Docker-backed integration tests could not run because Docker is unavailable in the current environment. just check reaches the generated-file cleanliness check, which reports the intentionally changed generated OpenAPI file against HEAD.
