Bug: Hardware details builds tab graph is not correct

[MarceloRobert]

The graph is usually bringing "No data" for the build tab, even though there is clearly build data for it (and if there wasn't any data it should return 0 for all commits). Example: https://dashboard.kernelci.org/hardware/acer-cb317-1h-c3z6-dedede?et=1771518600&st=1771086600&x[]=1

Sometimes it does bring data, but in the wrong quantity. Example: https://dashboard.kernelci.org/hardware/kubernetes?et=1771518600&hs=kub&st=1771086600&x[]=4
