Business Events AppId is the project unit id: copied with the model and shown by no command #1526
Description
Summary
The Business Events AppId is the project unit id, so it is copied with the model, and no command shows it.
Repro
cp app.mpr copy.mpr(or create apps from one template model).- Both apps subscribe to the same message through the Business Events module.
describe settingsandshow settingsprint no AppId.
Expected
describe settings prints the AppId; creating a copy (or mxcli new from a model) assigns a new project id.
Actual
The AppId equals the Projects$Project unit id, so two copies share it. The only static read is grepping mprcontents. Consumer-group competition between the copies is an inference; the broker behaviour was not measured.
Tested with: Mendix 11.15.0, mxcli v0.26.0 on macOS. Not retested on v0.27.0.

Issue Triage
Summary:
The Business Events AppId is taken from the project’s unit ID, so copying an .mpr file results in duplicate AppIds and no CLI command displays it.
