This pull request improves the style and functionality of the date range picker and the right panel in the AMIS editor. It uses CSS variables and mixins to adjust the font size and layout of the UI elements, and fixes some bugs and schema issues in the date range control plugin. It also imports the amis-ui style sheet to reuse the common variables and mixins.
