🐛 Fix extension __id path and simplify commonPricingArgs nil guard

Use "/extension/" (singular) in buildExtensionResources to maintain
backward compatibility with the pre-existing CSPM extension cache keys.

Simplify the nil-props guard in commonPricingArgs by substituting an
empty PricingProperties struct, so all nil-safe field checks handle it
uniformly without duplicating zero-value assignments.
