v0.1.30 - Throughput overview today-only mix cards; mix formula save 500 fix

Throughput Overview: Horse Mix and Grain Mix are now the first two cards and
show TODAY's output only. Removed the 7d/4w/6w/12w range selector; the cards
are fixed to Horse mix today, Grain mix today, Today, This week, 4-week average.

Mix Editor formula save: fix HTTP 500 on PUT /editor/mixes/{id}/formula. The
audit-diff path read the resolved formula by attribute, but the resolver returns
dicts -> AttributeError. Read by key and expire stale ORM state so the response
reflects the just-saved rows. Adds regression tests for both save branches.
