  ME system uploader for ComputerCraft (CC: Tweaked).

  Requires an "ME Bridge" peripheral (Advanced Peripherals) connected to the
  computer and wired to an Applied Energistics 2 / Refined Storage network.

  It periodically reads the network contents and POSTs them to the backend's
  /api/me-system/update endpoint.

  NOTE: the backend serves HTTPS with a self-signed certificate by default.
  CC: Tweaked validates TLS certificates, so either:
    * point API_URL at an http:// endpoint (run the backend with
      TLS_ENABLED=false, ideally behind a trusted reverse proxy), or
    * terminate TLS with a proxy that uses a certificate CC trusts.
