fix(review): correct predicted_gate_calls migration ref to 0137 (#8695)

Both predicted-gate-calls.ts and predicted-gate-agreement.ts carried a
comment pointing the predicted_gate_calls table at migrations/0132, which
actually creates the unrelated impact_map_query_cache table. The table is
created by migrations/0137_predicted_gate_calls.sql, so a reader tracing
the table's migration history was misdirected to the wrong file.

Closes #8675
