fix(form-add,cf-init,cfe-init): ExtendedPresentation + InterfaceCompatibilityMode

- form-add v1.2: ExtendedPresentation only for DataProcessor/Report/External* forms
  (Catalogs, Documents, Registers etc. don't have this property — platform rejects it)
- cf-init v1.1: InterfaceCompatibilityMode Taxi → TaxiEnableVersion8_2
  (matches all real configs: acc 8.3.20/24/27, erp 8.3.24)
- cfe-init v1.1: read InterfaceCompatibilityMode from -ConfigPath base config
  (analogous to existing CompatibilityMode auto-detection)
- Remove workaround in platform-cfe integration test (cf-edit modify-property)
- Update 162 snapshot Configuration.xml + 7 form metadata snapshots

Tests: 301/301 passed
