[FEATURE]: UI changes

[pratibhapandey16]

• Vertical scrolling should only be limited in each panel, no page scrolling
• Query bar and search section should always be visible
• Data configurations should have minimal width
• Data configurations did not yet fully follow UX design which should have fields drilldown
