fix: prevent Enter key from submitting form to non-existent /search route

Pressing Enter in the URL input submitted the form via GET to /search,
which has no route and returned a 404 ("NotFoundError: Not Found").
The download was only wired to the button's click handler.

Intercept the form's submit event, prevent the default navigation, and
trigger the same socket-based download. Enter now works like clicking the
download button. Logic extracted into a shared startDownload() function.
