Fix image display in HF Space iframe: samesite=none cookie + global image cacheRunning

HF Space runs the app in an iframe at hf.space embedded in huggingface.co.
These have different eTLD+1, so samesite=lax cookies are not sent on
cross-site requests — each API call arrived with a fresh session, meaning
the image uploaded in session A was never found by the subsequent
GET /api/image/{id} request (session B) → 404 → placeholder stayed visible.
Fix:
- Set samesite=none + secure=True when POLYSCRIPTOR_PROFILE=hf_space_demo
- Add global_image_cache as cross-session fallback so image retrieval
succeeds even if the session cookie is lost
Also restores multi-target drop zone (viewerScroll + viewerPlaceholder)
as secondary UX improvement from the earlier working version.

- Add TrOCR and Kraken engines (CPU-only, no GPU needed)
- Remove hf-space/ subdirectory from Space repo (content at root level)
- Replace full requirements.txt with minimal HF-Space-specific one
(torch, transformers, kraken, openai, anthropic, google-genai)
- Dynamic commercial API model fetching (no hardcoded lists)
- Updated Claude/Gemini/OpenAI fallback model lists
- Add comparison panel JS component
- Fix publish script: whitelist-based, clean deploy, no private files
