Marc-André Bombeck ebeb16daa3 fix(sleep): emit the per-night total, not a single stage, on the sleep tile and series
SLEEP_DURATION is stored in minutes, one row per sleep stage per night
(IN_BED / AWAKE / ASLEEP / CORE / DEEP / REM) since the HealthKit
category-sample ingest landed. The value is not cumulative, so reading
the single most-recent row surfaced one stage's minutes — never the
night. The dashboard sleep tile and the sleep series therefore showed a
fragment of the night rather than the night.

Add a shared `summarizeSleepNights` helper that groups the per-stage
rows by the wake-day calendar date in the user's timezone and sums the
asleep stages (CORE + DEEP + REM, plus a legacy bare-duration row),
excluding IN_BED and AWAKE per the AASM convention already used by the
sleep score. Wire it into:

- the dashboard summary tile, which now emits last night's time asleep
  in hours with an explicit `unit: "h"` and a per-stage breakdown for a
  future detail view;
- the sleep series, which now returns one point per night (time asleep
  in hours) plus a top-level `unit` for every kind so clients never
  infer the unit;
- the slim summaries slice, so the web dashboard tile and the insights
  overview read per-night totals (kept in canonical minutes there; the
  web tile converts to hours) — strictly more correct than averaging
  across stage rows, and parity with the iOS value.
