feat: make quest tracker movable, resizable, and right-edge-anchored

- Remove NoDecoration flag to allow ImGui drag/resize
- Store questTrackerRightOffset_ instead of absolute X so tracker
  stays pinned to the right edge when the window is resized
- Persist position (right offset + Y) and size in settings.cfg
- Clamp to screen bounds after drag
