Wake the scheduler on plan and dinner changes (MQ-177-01)

A swap, stored draft, or dinner method/minutes change (edit or grounding)
now calls Scheduler.Wake once committed, so a crock-pot dinner swapped in
for tonight is reminded at start_by minus 15 minutes rather than at the
next hourly pass. Adds a fake-clock test that swaps in a crock-pot
Quest-log dinner at 09:01 and asserts the start reminder at 09:15, once.
