The commercial schema uses uuid primary keys everywhere in this project
(all schemas: `@primary_key {:id, :binary_id, autogenerate: true}`), but
the Rust port bound SELECTs against commercial_links.id and
commercial_samples.link_id as i64. The f00 analysis step failed on first
contact with:
error occurred while decoding column 0: mismatched types; Rust type
`i64` (as SQL type `INT8`) is not compatible with SQL type `UUID`
Switched LinkLookupEntry.link_id and fetch_per_link_degradation's
parameter to uuid::Uuid, updated the sqlx::query_as tuple type, and
patched the test helper to build distinct UUIDs from a byte tag so the
no-range / aggregation / rounding tests still exercise the same
identity semantics without needing a real DB column.
