Marc-André Bombeck fbdcb31202 feat(import): add CSV measurement import with per-row status and dry-run ...

A self-hoster migrating from a spreadsheet or a meter export overwhelmingly
has CSV, which neither the JSON nor the Apple Health import covers. Add
`POST /api/import/csv` reusing the existing write loop and rollup re-fold.

The documented header is `type,value,unit,measuredAt[,glucoseContext,notes,
externalId]`, order-independent. measuredAt must carry an explicit ISO-8601
offset — a row without one is skipped rather than guessed — and is bounded by
the shared entry-instant validator. Glucose accepts mmol/L (converted to
canonical mg/dL) and weight accepts lb (converted to kg); any other
non-canonical unit is skipped, never mis-stored. An optional externalId
column makes a re-upload idempotent; without it a re-upload duplicates.

The response carries a per-row status envelope so a 2000-row file with three
bad rows imports 1997 and names the three. `?dryRun=1` validates and previews
the outcome without writing. The parse, validation, and unit conversion live
in a pure module so they are unit-tested without a database.

Settings -> Export & Import gains a third CSV card mirroring the JSON and
Apple Health cards, with upload, paste, preview, and a downloadable example.
The new route is documented in the OpenAPI contract.
