Prepares for a future electric pulse-reading device without needing
one yet: a new meter_window_consumption table stores real per-window
(Day/Night) daily kWh computed from hourly device telemetry before it
gets purged, and computeCost() now prefers real data over the tariff's
fallback_split_pct for whatever it covers, filling any gap (or the
whole thing, today) with the existing % split. Zero behaviour change
until a meter has mqtt_topic set and a TOU tariff assigned — the new
table stays empty and every calculation degrades to exactly the
current fallback-only path.
scheduler.js's computeDailyWindowSplit() buckets each hour's telemetry
delta into whichever tariff_rate_windows row its time-of-day falls
into (previously-unused start_time/end_time/days_of_week columns),
runs once daily before the hourly-aggregate purge.
