Review Comment:
Good catch, done. Both options are now `SECTION_SYSTEM`, resolved via
`FlinkOperatorConfiguration.fromConfiguration` (new `jarUriAllowedSchemes` /
`jarUriDisallowRestrictedHosts` fields), and read by the validator from
`configManager.getOperatorConfiguration()`. A new test in
`DefaultValidatorTest#testSessionJobJarUriValidationUsesOperatorConfig`
confirms a CR-supplied override of these keys is ignored.
