fix(scheduled-tasks): POST /cancel alongside DELETE, both idempotent#877vansin wants to merge 4 commits into

…potent Some reverse proxies swallow DELETE and return 405 HTML, which broke the dashboard's cancel button (`await res.json()` on HTML → "Unexpected token <"). Adds POST /api/scheduled-tasks/:id/cancel with the same implementation as DELETE, so the dashboard can use a universally-allowed verb. DELETE stays for API compat. Both spellings are now idempotent: re-cancelling an already-cancelled row returns 200 without touching the DB (previously bumped revision on every call, which would race with the dashboard's revision-conflict logic). test: adds POST /cancel path, DELETE idempotency (200 + same revision), and POST /cancel idempotency to the existing cancel-preserves-history test. Baseline (before this change) has 3 unrelated failures on this branch (`runs.length >= 4` data flake + non-overlap ordering) — this change adds 7 more expect() calls, all pass.

Superseded by fresh PR cherry-picked onto current main (feat/scheduled-task-edit was 2 weeks behind, contained already-merged commits). Same fix, cleaner base. |

The claimed Hub source fa6a07b contains seven fewer assertions than the reported 106—the seven /cancel assertions appear only later in this reviewed change—so an image embedding that SHA cannot both have been built from a clean fa6a07b tree and produce this result. This makes the required Docker evidence non-reproducible; rebuild from a clean reviewed source and record its actual commit.

When duplicate cancellation requests are routed concurrently to different Hub processes, both can read the row as active before either update commits, and this unconditional update then increments revision twice. The new status precheck therefore guarantees idempotency only for sequential retries; make the update conditional on the persisted status (or perform the check and update transactionally) so concurrent retries cannot mutate the row more than once.

If any mutated full-suite run fails for an unrelated reason—such as one of the existing ordering or run-count flakes—this helper treats the nonzero exit code as proof that the mutation was detected. As a result, a mutation whose targeted behavior remains completely untested can still be reported as MUTATION_RED; inspect the output for the expected assertion/test failure rather than accepting every nonzero status.

Fixes production 定时任务「取消」P0 (dispatch 通信狗 08342434). Paired with dashboard PR (link once opened).

Some reverse proxies in the delivery path rewrite DELETE to a 405 HTML response; the dashboard then calledawait res.json()on the HTML and blew up with "Unexpected token<", hiding the failure from the user (spinner stuck, no error surfaced).Fix in this PR

Hub must ship before or at the same time as the paired Dashboard PR. Once dashboard is on the new UI, cancel clicks hit
POST /cancel; if hub is still on the old handler, that path 404s and cancel appears broken again (different symptom, same user pain). Recommend: land this PR first, deploy hub to:9200, then deploy dashboard to:3100.Paired PR
