Description

Currently the `status.csv` is not written (such as for synchronous login node jobs) until all of the first job step jobs are completed, nor can cancellation be issued or checked until that point. Proposed changes:

- Write `status.csv` immediately after the study graph is created
- Update `status.csv` after synchronous login node job are completed
- Additionally check for cancellation between synchronous login node jobs

Research direction

No files or tests are named. Start by locating the workflow entry point that creates the study graph, writes status.csv, runs synchronous login-node jobs, and checks cancellation. Implement the three requested checkpoints, then verify that status.csv is created immediately, updated after synchronous jobs, and cancellation is checked between those jobs.
