Description

DateTime2 DatePicker no longer limits month select options when minDate specified.

Steps to see:

  1. Go to https://blueprintjs.com/docs/#datetime2/date-picker3
  2. Select min date "1 week ago"
  3. BUG: All 12 months are still displayed as options in the month select. Previously (DateTime 1), months would have been reduced to only the available months.

Research direction
Look into the DatePicker3 component in packages/datetime2/src/, specifically the month select dropdown logic. Compare with the older DateTimePicker implementation to understand how minDate filtering was applied. Check if the issue is in the month options generation or in the select component itself. Refer to the steps to reproduce in the issue body.
