feat(ui): support NEXT_PUBLIC_LITELLM_PROXY_URL to override backend URL in dev

Browse source 
The hardcoded localhost:4000 default in networking.tsx made it impossible
to run the frontend dev server against a port-forwarded K8s backend without
manually setting localStorage.

Add NEXT_PUBLIC_LITELLM_PROXY_URL as the top-level override in
defaultProxyBaseUrl. When set, all API calls (including the getUiConfig
discovery request) go to that URL. Falls back to the existing
localhost:4000 / NEXT_PUBLIC_USE_REWRITES logic unchanged.

Also fix getUiConfig to use proxyBaseUrl instead of defaultProxyBaseUrl,
so that litellm_worker_url set via localStorage is also respected for the
initial discovery request.
