fix(crm): commit LocalizedDateInput value live, not only on blur

The historical-invoice import (and any form whose date field has a non-empty
default like today) lost a typed date: the value was only pushed to the parent
on blur, so submitting while the field was focused — or before React
re-rendered after the blur-time setState — sent the stale default. Issued/
event dates came out as 'today' instead of the entered date.

Now commit as soon as a complete, valid date is entered (toIso returns '' for
partial input, so intermediate keystrokes emit nothing); blur still normalises
display + handles clearing. Applies to every LocalizedDateInput consumer.
