code-to10 reconcile: fix pre-existing worker F821 in playwright skipped-modified log branch

Target-line bug, not introduced by the replay: Worker._tenant_dirs
only receives project_id, yet the script_skipped_modified log line
used task.get("project_id"), raising NameError whenever seeding
reported a tenant-modified script (the refreshed sibling branch was
already fixed to project_id with its own regression test; this test
only covered the refreshed branch, so the full suite stayed green).
Fix mirrors the sibling (project_id) plus a regression test for the
skipped branch. Ruff F821 in worker.py is thereby cleared.
