Refactor code for improved readability and consistency

- Simplified error handling in `PostgresApContentQuery` and `SqliteApContentQuery` by aligning the formatting of `try_get` calls.
- Removed unnecessary line breaks and improved formatting in various repository implementations for better readability.
- Consolidated imports in `lib.rs` and `factory.rs` to maintain a cleaner structure.
- Enhanced consistency in async function signatures across multiple files.
- Updated test helpers and use cases to streamline code and improve clarity.
- Refactored `InMemory` repositories to enhance readability by aligning method implementations.
