Unit Tests - Python 3.12 - Group 3 has been failing at 98-99% on the nightly: the job hits the nick-fields/retry 40-minute per-attempt timeout and pytest is SIGTERM'd mid-test, so it looks like one flaky last test when it is actually a deterministic timeout (and the internal retry plus run-level retries can never succeed). Root cause is twofold: 1. .test_durations was last regenerated ~May 2025 and covered only 2,219 of ~9,500 current unit tests, so pytest-split weighted 77% of the suite at the 0.73s average. The expensive client-fixture tests (test_webhook.py, test_login.py - each pays a full create_app + lifespan boot per test, 60-120s late in a CI run) clustered into group 3's tail, making it ~8-10 minutes slower than its siblings (33:15 on 3.13, >40min on 3.12 which is additionally slowed by astrapy disabling SSL connection reuse on Python 3.12.0-11). The weekly store_pytest_durations workflow that should refresh the file has been dying at the 6-hour GitHub job limit every week (serial full-suite run no longer fits), so the file silently froze. This regenerates the file from real per-test wall-clock measured in the passing Python 3.13 nightly jobs (run 27246228762 attempt 1, all 5 groups, parsed from the -vv xdist logs: per-worker start-to-start deltas). 9,508 tests now have measured durations; old entries are kept where no new measurement exists. Simulated least_duration split goes from one outlier group to 5 even groups (~24.6 min each) with the >50s tests spread 1-2 per group instead of 7 in one. 2. timeout_minutes 40 -> 50 gives headroom for matrix-cell variance (3.12 runs ~20% slower than 3.13) so a slightly slow cell degrades gracefully instead of burning 2x40min and failing the whole run. Follow-ups (not in this PR): fix store_pytest_durations to run with xdist or split groups so it fits the 6h limit; investigate the in-worker degradation that makes client-fixture boots cost 8-12s early in a run but 60-120s after ~30 minutes.
