Designer: Show data toggle, column drag-drop, line spacing, font picker, canvas text fidelity 

- Replace the side Preview panel with a Show data toggle and record picker on
  the element toolbar; the canvas shows resolved values (read-only) or the
  {Column} tokens for editing, including Address Control lines.
- Drag a CSV column header onto the canvas to place a field, or onto an
  Address Control to add a bound line.
- Add a Line spacing field for Address Controls.
- Font is chosen through the standard Windows font dialog (family and size).
- Canvas text now scales with zoom and sits on the element's baseline, so
  size and position match the PDF.
