api-gateway: migrate YAML gen + provider core from deck-api (?endpoint=) to lk-api-gateway (REST paths)

- service_spec_gen: callAPI() auto-detects proxy vs REST mode by index.cfm presence
- core/client.go: buildURL() replaces all 4 ?endpoint= harcoded sites
- build-provider.sh: -ldflags -X main.version=${VERSION} for correct binary version
- 01_generate_yamls.sh (devops + root): Python auto-detect proxy vs REST
- 02_generate_resources_and_docs_v2.sh: pass -api-endpoint to doc generators
- 04_build_and_publish_docs.sh: normalize_api_endpoint without forced /index.cfm
- docs_template_gen + v2: -api-endpoint flag, hardcoded deck-api replaced
- provider.go (both): TODO(api-gateway) comments
- profiles/test/profile.env: NUBES_API_ENDPOINT -> lk-api-gateway-test
