Add two AI Agent features: prompt rewrite/scoring with before-after comparison, and self-contained HTML animation generation with sandboxed preview. Wire both through existing credits and auth patterns, with cross-page prompt handoff. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
This PR adds two AI Agent features to the Open SaaS demo app:
/prompt-optimizer) — Rewrites and scores user prompts (clarity, specificity, actionability) via OpenAI function calling, with a before/after comparison UI and per-user history./html-animation) — Generates self-contained HTML/CSS animations from natural-language prompts, previews them in a sandboxed iframe, and persists generation history.The two features are wired together: after optimizing a prompt, users can jump directly to the animation studio with the optimized text pre-filled.
Direction chosen: AI Agent (Prompt Optimizer + HTML Animation Generation)
