Marc-André Bombeck 143aefc709 feat(api): batched rollup-backed series endpoint to coalesce dashboard fetches ...

Add GET /api/measurements/series-batch returning every requested
MeasurementType's daily series in one response, so the dashboard chart
row stops issuing one self-fetch per chart. Extract the rollup-daily read
(per-source collapse, coverage probe + inline fold, live-SQL fallback)
into a shared readDailySeries reader so the single-type route and the
batch route read through the same path with no SQL duplication; the
single route now delegates to it. Cap the batch's per-type reads with
p-limit to protect the shared pool. Sleep stays on its per-night /series
adapter and is not batched.

HealthChart gains an optional preloadedSeries prop: when the dashboard
hands it a covered slice for the daily window it folds those rows instead
of self-fetching, keyed so a range-tab change re-fetches cleanly. Non-
dashboard mounts are unchanged (empty discriminator keeps the cache tuple
byte-identical). Register the endpoint in the OpenAPI table and regen the
spec; add unit + parity coverage for the batch route.
