Skip pytest coverage comment on fork PRs

[gomezzz]

Summary

• Fork PRs get a read-only GITHUB_TOKEN regardless of the job's permissions: pull-requests: write, so the Pytest coverage comment step fails with Resource not accessible by integration and marks the whole build job red even when every test passes (e.g. fix: lazy + crash-safe epoch formatting in eclipse-check debug log #215: 38 passed, 0 failures, 91% coverage, job still red).
• Gate the step on the PR head being in this repo. The action suggests pull_request_target instead, but that runs fork code with a writable token — not a trade worth making for a coverage comment.
• Same-repo PRs keep the comment exactly as before.

Related to #215, #222

Test plan

• This PR is same-repo → the Pytest coverage comment step still runs and posts the Coverage Report comment.
• After merge, re-run CI on fix: lazy + crash-safe epoch formatting in eclipse-check debug log #215 / Fix: use correct units for body_surface_temperature_in_K (K instead of K^4) #222 (fork PRs) → step is skipped and build goes green.
