   Bug Analysis

   az webapp list and az webapp show no longer return the appServicePlanId field in their output; it was replaced by serverFarmId. This regression was introduced in a change to _rename_server_farm_props() in src/azure-cli/azure/cli/command_modules/appservice/utils.py (referenced commit d86606f). The function's intent appears to be renaming/aliasing serverFarmId to also expose appServicePlanId in the output, but the current behavior drops appServicePlanId entirely.

   Fix guidance:

   • Locate _rename_server_farm_props() in src/azure-cli/azure/cli/command_modules/appservice/utils.py.
   • Ensure the transformation still adds/retains the appServicePlanId key (aliasing from serverFarmId) in the output of az webapp show and az webapp list, matching the pre-regression (v2.86) behavior.
   • Add or update unit tests in the appservice module's tests/ directory covering az webapp show / az webapp list output to assert appServicePlanId is present.
