emizzle e0e1487643 refactor: replace transaction modal reset functionality
The transaction component's `reset` functionality was meant ot reset a form when the modal was closed. It was difficult to manage and added extra overhead for each additional transaction modal created.

Instead of using reset functions, we can use Loaders to load and destroy the modal's as they are opened and closed. We do not need to keep them in memory and then also reset their functions. It creates a smaller memory footprint to destroy the object and reload on open.
