New POST /api/blog/from-url endpoint:
- Accepts url + topic in request body
- Fetches page server-side (no CORS, 20s timeout, redirect-follow)
- Strips script/style/nav/footer/svg; extracts readable text (~5000 chars)
- Extracts page title from <title> or <h1>
- Passes extracted content as structured additional_context to the
existing 16-step FO blog pipeline (same as manual generation)
- Returns immediately; LLM pipeline runs async
- Validated: smoke test fetched flexoptix.net/en/blog/, 5040 chars,
pipeline launched with llm_enhancing=true

- Button shows loading state "⏳ Fetching…" during API call
- Status line shows extracted char count after success
- Reuses pollBlogLlm() for step-by-step progress polling
