chore(deps): update crates and nix flakes

- Updated multiple Rust dependencies, including `opentelemetry`, `const-oid`, and `webpki-roots` for enhanced features and bug fixes.
- Upgraded `nixpkgs` and `crane` in the nix flake configuration.
- Removed unused dependencies and introduced missing dependencies for improved build integrity.
