Address review feedback on gallery-embed branch

- Composer.tsx: thread gallery through reply pills (hasMedia),
  post:create/draft:save analytics, missingAltError, and publish-fail
  logger annotation
- composer/state/composer.ts: surface a logger.warn when
  embed_add_images would exceed MAX_GALLERY_IMAGES (hard slice
  preserved); ascii-only comments
- maybeApplyGalleryOffsetStyles.ts: scope PostGalleryEmbedEnable gate
  to image-embed branches so gallery posts always get no-content offsets
- MessageOverlays.tsx: store reactionsTargetId instead of a frozen
  message snapshot; look up the live message each render. Memoize
  reportSubject on reportTarget+convoId so ReportDialog's parseReportSubject
  memo survives convo updates. Replace open-after-mount boolean with a
  ref keyed to id so reopening the same message reliably re-triggers
- ImageEmbed.tsx + ImageLayoutGrid.tsx: thread isWithinQuote through
  the 2-4 image fallthrough; explicit prop overrides the viewContext
  heuristic
- parseReportSubject.ts: flip the image attribute true for gallery
  embeds (top-level and post_with_media), matching the existing images
  branches
- AppIconSettings/index.tsx: restore the IconName casts the previous
  change dropped; IconName is still a literal union
- composer/photos/Gallery.tsx: wrap to a 4-column grid for n>4 so
  10-image previews don't crush remove/alt-text controls
- lib/api/index.ts: normalize gallery upload log nouns to image/images
