scheduled charging can also be used for discharge

Improve the ESS Scheduled menu to more clearly indicate
when a scheduled operation is active, what SOC is being
targeted, and to provide an option to self-consume
battery energy above the limit.

The use case for this is when a schedule with a lower
SOC limit follows one with a higher limit. The user may
want to self-consume down to the lower level.
