fix(form-validate): context-aware Check 12 — ExternalDataProcessorObject is error in config

Detect config vs EPF context by walking up from FormPath looking for
Configuration.xml. ExternalDataProcessorObject/ExternalReportObject are
valid in EPF/ERF but cause XDTO exception in configuration context.

- EPF forms: no warning (ExternalDataProcessorObject is correct)
- Config forms: ERROR with hint to use DataProcessorObject/ReportObject
- Fix test DSLs: compiled-form, table-form used wrong External* type
