Implement integrated HTTP server with self-signed CA certs in daemon

We should create an HTTP server that generates self-signed CA certs for the client, and shares those CA certs with the websocket transport.

This will allow secure context to be used, enabling the `VideoDecoder` API when accessing from a machine other than `localhost`.

Look for existing HTTP server and websocket transport code. Research how to generate self-signed CA certificates in Rust, likely using a crate like `rustls` or `openssl`. The server must share these certs with the websocket transport to enable secure contexts. Check how the `VideoDecoder` API is currently accessed and what changes are needed for remote machine access.
