Set the value for CommissioningModelInitialStepsHitto to "1" by default

[jcps07]

Copied from zigbee-alliance/distributed-compliance-ledger#522

According to the Matter Specification, section 5.7.1:

The Distributed Compliance Ledger entries for Standard Commissioning Flow devices SHALL include the CommissioningCustomFlow field set to '0 - Standard' and the CommissioningModeInitialStepsHint field set to a non-zero integer value, with bit 0 (Power Cycle) being set to 1.

The default value appears to be "0", and most of entries have this value set to 0, even while using "CommissioningCustomFlow" = 0.

Propose to set the default value to "1", instead of "0".

Suggested workaround: Set the value for CommissioningModelInitialStepsHitto to "1" by default, in the Web UI when adding a Model.
