fix(web): review-round attachment refinements

Body-portal the lightbox and toast so transformed ancestors cannot trap their fixed positioning (a lightbox opened from a chat message covered only the chat column); make the toast pointer-transparent; observe the rail element's own size instead of window resizes; consume vertical wheel ticks exclusively via a non-passive listener with LINE/PAGE delta normalization; keep the start position when the rail mounts over an existing draft; honor prefers-reduced-motion for the toast, remove-control, and paging; retry loads through the guarded load effect; note the deliberate promptError re-announce; pin the intake toast in the assembled snapshot; sync the superseded multimodal note and package docs.
