Keep a dropped dinner's name immutable and 404 a never-checked dinner

R-01: a Rotation check decided drop now records the dinner's name at the
decision in rotation_reviews.name (migration 0014, a table rebuild as 0012
did for suggestions; checks dropped before it take their dinner's name).
ListPassedNames and ListRecentPassedNames read that name instead of the
mutable dinners.name, so renaming the archived dinner no longer lets the
dropped dish back into a Side quest batch. A CHECK keeps a name on drops
only.

R-02: deciding on a dinner that has never had a Rotation check is now
ErrReviewNotFound, 404 not_found; a dinner whose checks are all decided,
such as a second decision, stays 409 no_pending_review.

Tests: TestLaterBatchNeverResuggestsRenamedDrop (drop, rename, next batch
still refuses the original name), TestMigrateRotationReviewName (0013 to
0014 upgrade and constraints), TestPostRotationReviewNeverChecked (404),
and TestDecideReview/TestDecideReviewRefused updated.
