Move seven completed items from the P1 and P2 sections into the
Completed section: in-memory jobs persistence, export endpoint tests,
tracked company admin tests, webhook integration tests, S3 storage
tests, auto-download path tests, and scheduler DatabaseClient refactor.
The P2 section now only lists the two genuinely open items: cursor-based
pagination (Issue #1669) and request validation (Issue #1670).
