Move TrustifyContext to its own module to avoid some circularity.

Add capabilities:

• Holds a Graph, the DB, a backend storage, and an ingestor
• Allow easy ingestion of docs from etc/test-data/

[bobmcwhirter]

This is the primary change, if you can sort through the noise. Making it easier to ingest documents for test setup.

[bobmcwhirter]

It should do yeah.

[bobmcwhirter]

I have a Stream. Maybe it's rewindable?

Can you remove the ingest fn in modules/fundamental/src/sbom/endpoints/test.rs as a part of this PR, too? Seems odd to exclude it.

@bobmcwhirter nevermind. after looking at it more closely, it doesn't appear to be a trivial change.
