improvement(config): consolidate Ollama URL and CSP socket/Ollama hardcodes

Add getOllamaUrl() to urls.ts and replace inline env.OLLAMA_URL fallbacks
in the provider and API route. Update CSP to use getSocketUrl(),
getOllamaUrl(), and a local toWebSocketUrl() helper instead of hardcoded
localhost strings.
