fix(data-entry): Show action buttons after saving new receipt

Vue Router reuses the component when navigating from create to view mode,
so onMounted doesn't run again and loadReceipt() was never called. This
left receipt.value as null, causing the Edit/Submit buttons to not appear.

Added a watcher for route.params.id that loads the receipt when navigating
from create to view mode, and resets the form when navigating back to create.
