Modes on: Controller._mode_roles() files the trade gate it just asked as
mode_gate; while it refuses, Home draws no grid charge and marks no cheap
quarter. Modes off: a charge after the last dear period is asked of the same
gate at its own start (homeview.leg_taken) and dropped when refused there.
Words: "Lowest/Highest price left" (EN, NL); a flat remainder on a dynamic or
day/night site is no longer called a fully fixed product.
No change to control decisions, commands or options.
