fix(gallery): forward imeta visual fields through video player to gallery

When the user long-pressed a playing video and tapped "Add Media to
Gallery", the share-action overlay (RenderTopButtons.kt:302) hard-coded
blurhash/dim/hash to null and built an inline MediaUrlVideo without
those fields. Result: the published ProfileGalleryEntryEvent (kind 1163)
carried only the URL, alt, e, m, and client tags — no x/dim/blurhash/
thumbhash — even when the source kind:1 imeta carried them.
