fix(pdf-server): hide viewUUID when interact disabled, widen annotations panel

- display_pdf result text no longer leaks viewUUID when the interact
  tool is not registered (model has no use for it).
- Annotations panel default width: 250px -> 500px (max-width:50vw
  still caps on narrow viewports).
