Add xref support, assembly/component views, and import tooling

- add_xref.php, edit_xref.php: xref record add/edit for stock content types
- admin xref group/source pages for stock_assembly and stock_component
- assembly_views/: auto_flow, fixed_grid, position_number, simple_list layouts
- Full assembly and component listing, tree, ordering, and detail pages
- Import tooling (ImportAssembly, ImportComponent, load scripts)
- liberty_plugins for assembly and component data types
- schema_inc.php updated; StockAssembly, StockBase, StockComponent,
  StockMovement classes updated with xref group/item/multiple renames
- Templates updated throughout for xref rename (source→item, group→x_group)
