Date Picker
Mantine DateTimePicker for /query evaluation time, flanked by previous/next ActionIcons for fast stepping.
DO
Expose previous/next Icon Buttons for temporal fields — scrubbing is more common than arbitrary date entry.
DON'T
Bury the time picker behind a second click on /query — evaluation time is the primary control.
