Merge pull request #1 from akncnkoc/proxy-url

Adds optional proxyUrl prop to support routing Google Places API requests through a backend proxy. Useful for hiding the API key on the client side. When proxyUrl is set, the component skips adding the X-Goog-Api-Key header, allowing the backend to handle authentication securely. Backward-compatible with existing usage.
