fix: only enable browser request streaming over HTTPS in Blazor WASM

SetBrowserRequestStreamingEnabled(true) requires HTTP/2, which browsers
only support over TLS (ALPN). When the target API uses plain HTTP,
the browser fails with ERR_ALPN_NEGOTIATION_FAILED on POST/PUT requests.

This change conditionally enables streaming only for HTTPS requests,
preserving the large file upload capability while fixing HTTP-only
development scenarios.
