Postgres batch inserts

Layer / File(s)	Summary
Chunked relationship and attribute writers internal/storage/postgres/data_writer.go	batchInsertRelationships and batchInsertAttributes chunk inputs into groups of up to 500 items and queue squirrel-built INSERT statements. Both methods return early for empty collections. Relationship inserts retain the conflict constraint, and attribute values use protojson marshaling.
