FLEX-WP-0036: Go module is github.com/netkingdom/access-engine; T02 consumer inventory

- module path renamed (no external importers); golangci local-prefixes
- ACCESS_ENGINE_RUN_TOPAZ_INTEGRATION replaces FLEX_AUTH_RUN_TOPAZ_INTEGRATION
- README title and identity paragraph reflect the landed renames
- docs/runtime-rename-inventory.md: per-consumer references by kind and order
- chart name, image package and /opt paths deliberately left for T05
