PR #191 added a today-window backfill to /api/medications/intake. The
v1.4.39.4 dashboard symmetry fix wires the exact same projection into
/api/dashboard/summary, which means two parallel routes can now race
the same (userId, medicationId, scheduledFor, REMINDER) row between
their existence probes and createMany calls. The @@unique on
(userId, medicationId, scheduledFor, source) is the structural
backstop; without skipDuplicates: true the loser of that race would
surface a constraint violation as a 5xx.
Pair the createMany with skipDuplicates: true so Postgres swallows the
rejected rows and both routes still return 2xx. Matches the same flag
the dashboard route ships with.
