fix: correct partition names for dynamic partitioning

- Updates `DROP TABLE` and `INSERT INTO` scripts in `tests/integration_test.rs` to target `objects_s_below_100000` and `objects_s_above_100000`.
- Matches the native PostgreSQL partition naming convention established by `ai_infra::divider_sql`, resolving `relation does not exist` test failures during teardown/insertion.
