­čŹ»Sidebar UX improvements

Rearranged a few things in the sidebar to make it easier when creating tables & columns: 

  • Overhauled the table name edit component
  • Removed the drag handler for reordering the tables and columns. Instead, you can now just reorder by dragging anywhere within.
  • Hid secondary actions are in a Dropdown - this newfound 'space' for additional action buttons also paves way for the next upcoming features 👁️‍🗨️
  • Added a new dropdown within the top bar, especially useful for performing the common actions like adding a column or index without having to scroll to the bottom
