Quick/Bulk Edit: Fix inability to quick edit draft post date.

Follow up to [56022] to fix inability to set a date/time in quick editing. Allow a user to set a quick/edit date while preventing accidental date assignments per the original intent.

Props tristanleboss, ivanzhuck, tibbsa, sabernhardt, sergeybiryukov, oandregal, khokansardar, joedolson, shailu25.
Fixes #59125. See #19907.
