createSubmissionHandler

Creates an Observable that handles form submission with optional submission action.

This utility encapsulates the submission handling logic:

• Listens for submit events from the event bus
• If a submission.action is configured, wraps it and uses Angular Signal Forms' submit()
• Handles both Promise and Observable returns from the action
• Uses switchMap to cancel any in-flight submission when a new one starts

The returned Observable should be subscribed to with takeUntilDestroyed() in the component.
