chore: remove unused rand dependency and update crates

- Removed `rand` dependency from multiple `.toml` files and updated relevant imports to use `rand_core::OsRng`.
- Updated OpenTelemetry dependencies to latest versions and refactored SDK initialization to use `SdkLoggerProvider`.
- Bumped versions of several dependencies including `clap`, `awc`, `ring`, and `smallvec` for compatibility and features.
