[desktop] Use custom Tauri command for HTTP requests instead of http-client plugin

Replaced the http-client plugin, as it does not support keep-alive connections.
Each request opened a new TCP connection to the service, which was inefficient.

The new custom `send_tauri_http_request` command, exposed to the UI, uses an application-wide `reqwest::Client`, which supports idle (persistent) connections.
