feat: Configure Ollama URL within provider config

This change simplifies the Ollama configuration by moving the url parameter into the ollama provider section within LLM_CONFIG. It also increases the Ollama timeout from 30 seconds to 120 seconds. The top-level ollama_url, timeout, and max_retries configurations are removed, as these are now managed within the ollama provider config.
