feat(iace): Einsatzbereich / Branche — filtert branchenspezifische Patterns

Neues Feld "Einsatzbereich" auf Interview-Seite (Sektion 7) mit 15 Branchen.
Pattern Engine bekommt MachineTypes aus MatchInput → branchenfremde Patterns
(Medizin, Aufzug, Bau etc.) feuern nur wenn die Branche ausgewählt ist.

Refactoring: iace_handler_init.go aufgeteilt in init + init_helpers (LOC-Limit).
