Use configured HTTP clients for all MCP OAuth requests (#35814)

## What changed

- Require callers to provide an HTTP client for MCP OAuth discovery and login, removing the separate direct `reqwest` path.
- Use the shared `http` and `url` types throughout the MCP client and drop its direct `reqwest` dependency.
- Preserve configured MCP headers when routing OAuth discovery through the provided client.

## Testing

- Add coverage that routed OAuth discovery forwards configured headers.
