Add Dependency-Track as default project

### Current Behavior:
When starting a fresh instance of Dependency-Track, there are no projects in the portfolio.

### Proposed Behavior:
Add Dependency-Track as default project to every new portfolio, with the SBOM that has been generated during the build (should be in the resources folder).

When a new critical CVE-vulnerability is reported, companies want to know whether any of the applications within their application landscape are affected by this vulnerability. Dependency-Track is part of this application landscape, so I think it should be part of the portfolio.

This project can also be used as an example project for users who want to quickly try out Dependency-Track without generating an SBOM themselves.

Maybe the project can be made read-only, but this would take more effort to implement. I’m also not sure whether the front-end and API server should be added as separate projects, or all components should be added to the same project.
