Summary

• Row Details shows a clock beside the calendar for a time of day and a timestamp: hour, minute and second spin buttons in a popover, two digits each, 24-hour like the value text. A date, a duration (MySQL TIME) and a locked cell get none.
• It opens on the value's time, or now for NULL and DEFAULT. Set, or Enter in a field, writes the value as typing would, into the row and field it opened on only.
• Only the clock in the text changes: day, fraction, offset and era stay. The clock is found by the text's own form, so a year past 9999, T, one-digit parts and SQLite text such as a timestamp in a TIME column keep every other part.
• A day without a time gets the time after it. Text with neither (NULL, infinity) becomes a new value: today for a timestamp, and the local offset at that moment where the column stores one.
• Enter goes through the popover's default widget; the icon is in the set all_icons_resolve checks; field and button labels carry a translation context.

Test plan

• row_detail::tests unit tests: only the clock changes across text forms, a value with no time, the offset of the set moment across a DST change, reading the time, where a clock is offered.
• Widget tests: opens on the value with two-digit fields and Set writes it; Enter in a field writes it; a page that takes the row closes the clock and writes nothing.
• verify.sh build, test tablepro row_detail (55 passed), test tablepro all_icons_resolve, lint.
