People aren't good with 24h. Default Clock-In/Out are now AM/PM dropdowns (15-min
grid) instead of 24h float_time inputs. Stored value stays the float-string
(e.g. '9.0'), so all downstream float(get_param(...)) reads are unchanged;
persisted manually with get-snap for any off-grid value. Bump 19.0.4.0.3.
