* fix: ensure HTTP requests use proxy env vars
Updated all instances of `http.Transport` to include the `Proxy` field set to `http.ProxyFromEnvironment`. This ensures that the application respects proxy configuration defined by the `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY` environment variables.
### Changes:
- Modified `http.Transport` initialization across the codebase to use:
```go
Proxy: http.ProxyFromEnvironment
```
- Ensured TLS configurations remain intact by preserving `TLSClientConfig`.
### Why:
- Previously, HTTP requests bypassed proxy settings due to missing configuration in the transport layer.
- This fix enables compatibility with proxied environments, aligning with standard Go behavior.
### Impact:
- All HTTP and HTTPS traffic now adheres to proxy settings.
- Domains listed in `NO_PROXY` bypass the proxy as expected.
### Verification:
- Tested with proxy environment variables set (`HTTP_PROXY`, `HTTPS_PROXY`).
- Verified requests route through the proxy and `NO_PROXY` works as intended.
