Fix parsing score_cap (#2033)

# Description
@fhenneke noticed that our `score_cap` is [parsed
wrongly](https://production-6de61f.kb.eu-central-1.aws.cloud.es.io/app/discover#/doc/c0e240e0-d9b3-11ed-b0e6-e361adffce0b/cowlogs-prod-2023.11.01?id=icFRiosBGP6wkTcjJhYX).

Value `1e16` is parsed as `18446744073709551616` due to
decimal/hexadecimal misconfiguration.
