Updated type hints to include `Union` for rollouts and attempted rollouts across multiple files. - Improved `query_rollouts` and `get_rollout_by_id` methods to return `AttemptedRollout` where applicable. - Added `query_resources` method for resource management in `DatabaseLightningStore`. - Refactored `as_attempt` and `as_rollout` methods to utilize `model_dump` for better serialization.
