fix(form-compile,form-validate): warn on invalid XDTO types, add Check 12

form-compile now warns when model uses runtime types like
FormDataStructure that don't exist in XML schema. Expanded cfg:
regex to cover all 25 known prefixes.

form-validate adds Check 12 — validates all <v8:Type> values:
ERROR for known-invalid types, WARN for unrecognized bare types,
pass-through for unknown namespaced types (future-proof).

Updated SKILL.md with full type reference and invalid type warning.
Updated docs/1c-form-spec.md with missing type groups.
