test(e2e): use pressSequentially for email autocomplete field

fill() sets the value atomically without firing real keyboard events,
so NcSelect's @search handler (driven by vue-select's input event)
doesn't trigger reliably in CI where the component may still be
mounting. pressSequentially() types character by character, firing
actual keyboard events that vue-select observes consistently.

Also removes the workaround that waited for the form to close before
opening the second dialog, which was masking the same root cause.
