Add git commit to the /status endpoint

[staffik]

Currently for release builds, the status endpoint displays the release tag without the information about the exact commit from which the binary has been built, e.g.

$ curl -s 10....:3030/status | jq -Mr .version
{
  "version": "2.4.0",
  "build": "2.4.0",
  "rustc_version": "1.82.0"
}
