fix(ui): fix place() method call - remove invalid width parameter

Fix the "width and height arguments must be passed to the constructor"
error by using proper place() geometry parameters.

The place() method doesn't accept width/height parameters - these
must be set in the widget constructor only.

Changes:
- Remove invalid width parameter from place() call
- Use relx=1.0 to position at right edge of parent
- Use x=-panel_width to offset left by panel width
- Use anchor="nw" (northwest) for proper positioning
- Widget width is already set in constructor via super().__init__()

The panel now appears correctly at the right edge of the window.
