feat(app): show each batch's story as a composite timeline

The Movement log (history + provenance DAG) was recorded but invisible.
A new history sheet on every lot tile narrates the batch: movements,
germination tests, storage checks and how it entered the collection
(origin attached), most-recent first. Two one-tap chips record 'sown
today' / 'harvested today' — the first UI door to the sown/harvested
movement types. No schema change; one-shot reads only (no live
subscriptions in a transient sheet).
