This PR

A date or time question leads to a group of follow-up questions when the answer lies within a range, both limits included. Each range is a row below the answer field with a start, an end and the same select as on options; either limit can be left out. Ranges may overlap, then all their groups are shown. A time range across midnight is written as two ranges, which the editor says.

• condition date_range with min and/or max in the format of the question (Y-m-d, H:i); the start must not be after the end;
• questions that ask for a range of dates or times have no follow-up questions, and the editor offers only one of the two;
• date and time questions of old forms (datetime) get no follow-up questions, as suggested in Conditional questions: base with radio and dropdown questions #3833 (comment);
• matching cases added to the shared fixture, docs and tests.

Tests

• PHPUnit passes, except the 15 IUserFolder errors main has as well on the test instance.
• php-cs-fixer, psalm and vue-tsc show no new findings compared to main; eslint is clean; the build works.
• Tested on a running instance: a date range leads to a group and is stored; axe reports no violations from this stack.
