🧹 Remove deprecated and unused combined_lifespan alias

[bashandbone]

🎯 What: Removed the deprecated combined_lifespan backward compatibility alias and its comment in src/codeweaver/server/lifespan.py.
💡 Why: This assignment (combined_lifespan = http_lifespan) is no longer used. Removing it eliminates dead code, improves code health, and reduces potential confusion regarding the module's API.
✅ Verification: Verified by checking references in the codebase (it was completely unused) and running uv run pytest tests/unit/server/ --no-cov. All 32 server-related tests passed, ensuring no functionality is broken.
✨ Result: A cleaner lifespan.py without deprecated aliases, leading to better maintainability and readability.
