Drop zone now has three explicit visual states: empty (default cloud +
instructions), ready (large file icon with a checkmark badge, filename in
big, size + click-to-replace + remove button, solid emerald border and
tinted background), and error (red icon + message, auto-clears after
2.5s). Covers both drag-drop and click-to-browse flows, validates size
client-side, and scales up slightly during dragover.

Publish form now uses a single dashed drop area for .html uploads
(click-to-browse fallback included). Removes the paste-HTML textarea
since real artifacts always come from a file. Server-side multipart
handling is unchanged; the `file` form field already took precedence.
