Stage 2 of the HRDPS plan. Mirror of hrrr_profiles for HRDPS-derived
rows so HRDPS can be dropped/reprocessed without disturbing the 4500+
HRRR profiles already in prod. Same column set, same indexes,
PARTITION BY RANGE (valid_time) with quarterly partitions starting at
the deploy quarter.
Schema follows the @primary_key {:id, :binary_id, autogenerate: true}
convention and the same set of derived fields HrrrProfile carries
(surface_refractivity, min_refractivity_gradient, ducting_detected,
duct_characteristics, etc.) so the rest of the pipeline can consume
HRDPS-derived rows interchangeably with HRRR-derived rows.
Unique constraint on (lat, lon, valid_time) is enforced at the DB
level via the partitioned index; schema-level unique_constraint/2
matching against changeset errors doesn't apply because the
partition's index name varies per partition. Production upserts go
through `on_conflict: {:replace_all_except, ...}` per project
convention.
