fix: Disable default features for tokio-rustls and use ring provider

- Disable default features for tokio-rustls (removes aws_lc_rs dependency)
- Use only ring feature for better cross-platform compatibility
- Update TLS setup to use rustls::crypto::ring::default_provider()
- Follows tokio-rustls best practices for dependency management

This ensures better Windows compatibility and smaller binary size.
