TimeFieldWidget class

time. Flutter's own showTimePicker, so no dependency — but it offers neither bounds nor seconds, so both are handled here:

Bounds clamp the pick. The dial cannot be restricted, so a time outside [minDate, maxDate] is pulled to the nearest bound the moment it is chosen, and the field shows the clamped value immediately. The alternative is storing a value the server refuses, and bounds are published as hints, not as validation rules — nothing else would catch it.
Seconds decide the wire format, not the picker: showTimePicker cannot pick seconds at all, so a seconds: true field reports HH:mm:ss. That matches TimePicker's own H:i:s format, which is what the server parses. Stored seconds are kept when the user leaves the hour and minute alone — opening the picker and pressing OK must not quietly rewrite 14:05:30 to 14:05:00.

The reported value is HH:mm (or HH:mm:ss) — never DateTime.toIso8601String(), which would invent a date the panel never chose.
