* fix(security): allow disabling API docs in production via GATEWAY_ENABLE_DOCS
Expose /docs, /redoc, and /openapi.json only when GATEWAY_ENABLE_DOCS=true
(default). Setting GATEWAY_ENABLE_DOCS=false disables all three endpoints,
preventing unauthorized API surface discovery in production deployments.

* test(security): add unit tests and docs for GATEWAY_ENABLE_DOCS
Add 7 tests covering default behavior, env var parsing (case-insensitive,
fail-closed), endpoint visibility, and health endpoint independence.
Update CONFIGURATION.md and CLAUDE.md with the new toggle.
