Refactor Retro Suggest Groups

Similar to how inspirations have a built-in prompt & then you can pass in your own prompt on how to write an inspiration card, we need the same for retro reflection suggested groups. imagine if you hover a card & then can click an icon in the upper right. It opens a modal with 2 radio buttons & 2 checkboxes: (x) Group Semantically (  ) Group by Prompt: ____________ [x]  Only Group in same column [  ] Group immediately (vs. suggestions on hover)
