Jun-te Kim b1ff711260 perf(modelling_e2e): batch SubTask bookkeeping to stop per-property writes
Even after batching the data writes, the handler still wrote to the DB per
property through the orchestrator's SubTask bookkeeping: create + start +
complete each self-committed, and _cascade re-listed every sibling and re-saved
the parent on every transition — ~5 writes per property plus an O(N^2) cascade.

- TaskOrchestrator.run_subtasks: create all children in one INSERT, run each
  (failures isolated per child), then persist all terminal states in one bulk
  save and cascade the parent once. Children go WAITING -> terminal; the
  transient IN_PROGRESS row is never written.
- SubTaskRepository.create_many / save_many (bulk INSERT / bulk fetch + update).
- _cascade short-circuits when the Task is already FAILED (terminal) — skips the
  sibling roll-up entirely.
- modelling_e2e handler fans out via run_subtasks instead of per-property
  create_child_subtask + run_subtask.

Per N-property batch the SubTask bookkeeping drops from ~5N writes + an O(N^2)
cascade to ~2 writes + 1 cascade.
