fix(migrations): reference the mapped measurement_type enum in the reminders table

The generated 0162 migration typed the measurement_reminders.measurement_type
column as the Prisma enum name "MeasurementType" rather than its @@map'd
Postgres type "measurement_type", so a fresh migrate deploy failed with
'type "MeasurementType" does not exist'. Unit typecheck passed (the generated
client is unaffected); only a real-Postgres deploy surfaces it. Verified the
full 0001-0166 chain applies clean against Postgres 16.
