🛠️ Description
Updates the FinOps hub deployment to accept flexible VNet CIDR sizes (/8 -> /26) instead of requiring only /26. This change enables users who deployed with larger CIDR blocks (like /24 for Power BI VNet Data Gateway support) to upgrade to newer versions without being blocked by validation errors.
The fix maintains the existing subnet calculations to ensure backward compatibility - only the validation is changed to be more permissive.
Fixes #1668
