v0.9.4 — Benchmark reads the rate helper

The effective-rate hint read vs €0.3578 day rate with the rate written into the JS. Rates moved into input_number helpers precisely so a price change is four edits and no code — and this line would have quietly contradicted them at the next change, on the one tile whose job is to be compared against it.

It now reads input_number.rate_day, and drops the comparison rather than inventing one if the helper is missing:

EFFECTIVE RATE
0.1833 €/kWh
yesterday, all-in · day rate €0.3578
