feat: Introduce SequencerClient for enhanced account management and transaction querying

- Added SequencerClient class to handle asynchronous account reads and transaction queries.
- Updated NewPositionRuntime to integrate SequencerClient, allowing for improved wallet account management.
- Modified existing tests to accommodate changes in the new position schema from v1 to v2.
- Enhanced QML tests to validate new position form behavior with updated holding selections and context handling.
- Refactored code to ensure compatibility with the new SequencerClient functionalities.
