Keep Pass history immutable and replenish atomic with decisions

Fixes the three review findings on 50399b6 (pull request #102):

- A batch now rereads every declined name inside its storing transaction,
  so a Pass committed after the batch read its input but before it stores
  can no longer let the passed dish into the deck (SQ-01).
- A decision that leaves the deck under five creates the replenish batch
  and its job in the decision's own transaction, so a decision is never
  recorded without the replenish it calls for; when they cannot be
  written, neither is the decision, and a retry decides again (SQ-02).
  StartBatch commits the batch with its job the same way, replacing the
  mutex and the fail-on-enqueue cleanup. jobs gains Kind.EnqueueTx and
  Kind.Wake for this.
- Migration 0012 gives each suggestion the name its dish was suggested
  under; declined names for batches and the household context's passed
  list read it instead of the dinner's mutable name, so renaming a passed
  dinner no longer erases it from dedupe (SQ-03).
