feat: configurable LLM model, SERP cache TTL, structured logging, fix patent_id type

- Make LLM model configurable via MODEL env var, default anthropic/claude-3.5-sonnet (#12)
- Expose SERP cache TTL as SERP_CACHE_TTL_HOURS env var, default 24 hours (#13)
- Fix Patent.patent_id type annotation from int to str in types.py (#14)
- Replace all print() calls with structured logging in analyzer.py and llm.py (#11)
- Add LOG_LEVEL config with basicConfig setup in config.py
- Add model and serp_cache_ttl_hours to config.py

-#### Patent PDF Storage

-The API stores downloaded patent PDFs in a `patents/` directory. In Docker,
-this is mounted as a bind mount (`./patents:/app/patents`) so that PDFs persist
-across container restarts.
-
-If you deploy to a different environment, ensure the `patents/` directory is a
-persistent volume. Without it, PDFs will be re-downloaded on every analysis.
