feat(standards): codify codegen, ship generic Tier-B infra, add get_app_template + prompts; fix docs:// regressions

P0: fix doc:// -> docs:// across standards src/server/registry and regenerate stale mongo-ops bundle. P1: build recipe + spec-first routing now document the openapi-first codegen fast path (models/routes with --inject-request/--package). P4: CRUD template documents the model-vs-document id rule (BaseDocument owns id). P5: authless guidance (omit security keys). P6: template gains generic infra (http_cache, keyed SSE bus, KV port+in-memory+Redis), interfaces/openapi.py + .dockerignore + generic build test registered as components, and a get_app_template tool; genericity matrix marks LLM pool + human-in-loop as reference-app patterns. P7: intake/build/start_app/trial prompts. P8: template ships tests/integration/test_openapi_app_builds.py. Rebuilt standards + openapi-first bundles and re-collected.
