fix: lazy-compile API method scripts and prefix composed alarm trigger attributes

- InboundScriptExecutor lazy-compiles scripts on first request, solving
  the multi-node problem where methods created via CLI/UI were only compiled
  on the ManagementActor's node, not the node handling the HTTP request.
- ManagementActor hot-registers API method scripts on create/update/delete
  for the local node.
- FlatteningService prefixes the "attribute" field in composed alarm trigger
  configs with the composition instance name so alarms evaluate against the
  correct path-qualified attribute (e.g. CoolingTank.Level not Level).
