Extract 3 entity composables (useEntityCustomFields, useEntityDocuments,
useEntityProductDisplay) and entityCustomFieldLogic utility shared across
ComponentItem (1336→585 LOC) and PieceItem (1588→740 LOC).
Improve type safety in edit/create pages with explicit casts.

When a category has linked items (pieces, components, products),
enable restricted mode instead of blocking all edits:
- Allow adding new custom fields
- Lock existing fields from modification or deletion
- Hide add buttons for products, pieces, and subcomponents
- Display informative message about restricted mode

- introduce product catalogue pages, management view entries and shared product composables\n- wire product selection into component/piece flows and machine skeleton requirements\n- display linked product metadata and documents across machine, component and piece views\n- generalize model type tooling to handle PRODUCT category
