Pull request overview

This PR moves Firebase and SerpApi secrets/config out of client-side source files and into environment variables served by the Flask backend, and adds local-dev support files.

Changes:

• Replace hardcoded Firebase web config in the browser with a runtime fetch from /api/firebase-config.
• Read SERPAPI_API_KEY from environment instead of embedding it in app.py.
• Add .gitignore, .env.example, and a requirements.txt file.
