Overview

The crate has been archived and we have to migrate to rustls-pki-types: rustls/pemfile#61
This resolves the cargo-deny error.
We use it only on dev-deps so there's no effect on users.

Pull request overview

This PR replaces the archived rustls-pemfile crate with direct usage of rustls-pki-types types in response to the deprecation notice at rustls/pemfile#61. The migration simplifies TLS configuration setup in tests and examples by using rcgen's DER output directly instead of converting to PEM and parsing back.

• Replaces rustls-pemfile dependency with rustls-pki-types version 1.13.1 in dev-dependencies
• Simplifies certificate/key handling by using DER format directly from rcgen
• Removes unnecessary PEM parsing and BufReader usage
