feat(plugins): enhance SMS sending functionality with raw HTTP handling

- Added support for using the `net` module in the `send-sms` plugin to establish raw HTTP connections.
- Refactored the `ztePost` function to `zteHttpPost`, allowing for custom HTTP request formatting and improved error handling.
- Introduced a new utility function, `httpBodyFromRaw`, to process raw HTTP responses effectively.
- Updated the `script-sandbox.js` to allow the use of the `net` and `node:net` modules in the sandbox environment.
