Marc-André Bombeck 6e75463fef fix(api): pass aggregate grain as a SQL literal to date_trunc ...

The `aggregate=daily|weekly|monthly` branch on `GET /api/measurements`
500'd in production for every grain. Two root causes that the
mocked-`$queryRaw` unit suite hid end-to-end:

1. `date_trunc(${truncUnit}, …)` passed the grain as a bound
   parameter; Postgres rejects — the unit argument must be a SQL
   literal. Switch to `Prisma.raw` for the unit string; safe because
   the grain is upstream-restricted to the `AggregateGrain` Zod enum.
2. The `daily → day` mapping ignored the `weekly` and `monthly`
   forms; Postgres rejects those as units. Map all three grains to
   the singular Postgres unit (`day` / `week` / `month`).

The user-id cast `${type}::"MeasurementType"` also referenced a
non-existent type name; the actual Postgres enum is `measurement_type`.
Corrected alongside.

Add `tests/integration/measurements-aggregate-daily.test.ts` against a
real Postgres so every grain compiles + executes end-to-end. The
mocked unit suite stays for the route-shape contracts.
