{{-- v1.6 — Split components into two sections (Semi-Finished / Raw Material) + help popover. --}}
{{-- v1.5 — Add Type column in components table; components array includes material_type for auto-badge. --}}
{{-- v1.4 — Fix: @push('scripts') → @section('scripts') (layout uses @yield, not @stack). --}}
{{-- v1.3 — BOM code readonly plaintext (auto-generated, not editable). --}}
{{-- v1.2 — Fix: $p->product_name; JS usa $components (RM) separado de $products (FG) del header. --}}
{{-- v1.1 — i18n: replace hardcoded "— Seleccionar —" with __('manufacturing.common.select'). --}}
{{-- v1.0 — Formulario edición BOM con líneas dinámicas pre-cargadas. --}}
