Summary by cubic

Adds EstimateConversionCostAction to centralize conversion cost estimation behind an application-layer action. Fulfills CONV-227 by providing a single entry point for UI and API to request cost estimates.

• Migration
  • Replace direct uses of ConversionCostEstimator with EstimateConversionCostAction (call handle(file, converter, options)).
