[FEATURE]

Due complex schema now i had to move through zoom in, zoom out
1. Add a button in the floating bar to navigate across the canvas through mouse movement.
2. Add movement/navigation upon moving the cursor across canvas edges

Start by locating the floating bar and the canvas interaction entry points, then inspect how zooming and existing movement are handled. Implement the requested floating-bar navigation and edge-triggered cursor movement; it is done when both navigation methods let users move across a large schema canvas.
