ci: add PROSE SOP compliance workflow

Run the PROSE platform-overview integration tests on every push/PR,
log the SOP-backed Expectation results to Provenant, and print a
compliance report.

- Trigger: push to main, PRs, and workflow_dispatch
- Restores Provenant DB from cache
- Runs scripts/log-prose-results.ts
- Prints provenant compliance report
- Uploads updated graph DB as artifact
