feat: remove AI thumbnails, rewrite frontend with React (v1.3.0)

Remove all AI thumbnail generation infrastructure (too expensive,
poor results) and rewrite the public-facing article feed as a React
SPA mounted via WordPress shortcode.

Changes:
- Remove thumbnail generation, OG scraping, and image download code
  from fetcher, LLM, and admin classes
- Replace server-rendered PHP templates with React component
  (PeptideNewsFeed.jsx) using WordPress-bundled React/ReactDOM
- Add Babel build pipeline for JSX transpilation
- Update REST API to serve ai_summary instead of thumbnail fields
- Redesign public CSS: clean card layout, loading skeletons,
  dark mode, responsive, no thumbnail imagery
- Remove dead admin settings (llm_image_model, thumbnail_fallback)
- Fix call_openrouter() visibility for Content Filter cross-class use
- Bump version to 1.3.0
