Add Auto-Renewal Boolean CLM Attribute to CLM Data Model

Problem:
Currently, auto-renewal CLM attribute in contracts is not represented as a dedicated boolean attribute in the XML/data model (for example in xml output of step find document). Instead, it is implicitly derived from related fields such as auto_renewal_count and auto_renewal_unit. This creates challenges when building workflows or performing change detection, as users must implement custom logic to infer whether auto-renewal is enabled or disabled.

Proposed Solution:
Introduce a dedicated boolean attribute (e.g., autoRenewalFlag) in the CLM data model and XML output:

• true → auto-renewal is enabled
• false → auto-renewal is not enabled
