Revalidate the draft pool on save, refuse duplicate swaps, refresh the Quest log after a draft

Feature 14 integration fix (Maestro 857e4c33-e250-46ec-b5ea-7dd4f3b719d9).

- F14-01: storeDraft re-reads the draft pool (ListDraftPool, the same
  eligibility rule draft_week was given) inside the save transaction. A
  day whose dinner was archived, moved to tried, or planned on another
  current or later week while draft_week ran fails the job with the new
  retryable reason pool_changed and stores nothing.
- F14-02: Swap refuses a dinner already on another day of the week inside
  the write transaction; the API answers 409 dinner_already_planned.
- F14-03: a finished draft invalidates the Quest log query, as the swap
  path does, so the tablet strip and desktop panel drop dinners it planned.
