fix: use unique collection names in aggregation, relationship, and SharedTables tests

- Aggregation tests: add per-worker unique suffix to dp_agg_* and
  dp_grpby collection names to prevent cross-worker conflicts
- OneToMany relationship tests: use uniqid() for teams/players/blogs/
  posts/products/categories/authors/books/libraries collection names
  in all testPartialUpdate* and testOneToManyAndManyToOneDeleteRelationship
- SharedTables: use unique name for multiTenantCol collection
