Fix: project decommissioning and resource inventory were ignored

v0.12.1-beta

Fix: project decommissioning and resource inventory were ignored. Both commands added in 0.12.0 (destroy-project and the managed-resource inventory) were understood by the agent but filtered upstream by the communication router, which silently rejected them as an "unknown type". As a result, fully deleting a project and detecting orphan resources on the admin side had no effect. Both commands are now accepted end to end. A test guarantees that every routed command is also allowed by the router, to prevent this kind of regression.
