Move Odoo operation status reads to FastAPI

[cbusillo]

Summary

• Move Odoo stable-bootstrap and target-replacement operation status GET reads to native FastAPI routes.
• Remove the corresponding legacy WSGI read matcher/handler branches while keeping POST enqueue poll URLs unchanged.
• Add native FastAPI coverage for response shape, auth/authz, missing records, read-only store gates, OpenAPI, and fallback precedence.
• Update service-boundary and compatibility-retirement docs.
