fix(inventory): raise AssignSpoolModal z-index so it sits above the mobile sidebar drawer (#1336)

Both used z-50, so DOM stacking-order let the sidebar bleed over the
  modal on narrow viewports. Bumped to z-[100] to match the convention
  used by GitHubBackupSettings, FilamentHoverCard, and the Layout
  confirmation modal.
