Stock package: assembly/component model, package-level xref, imports, print BOM

- LibertyXrefInfo/LibertyXrefGroup: package-level guid support ('stock')
  so stgrp, supplier, kitlocker groups are shared across SA and SC
- schema_inc.php: stgrp group with KLG01-28, supplier consolidated to 'stock'
  level, kitlocker moved to 'stock', duplicate #PN/#PR removed
- StockAssembly::getList(): non_root_only and show_empty fixes for standalone
  assemblies (no gallery hierarchy)
- StockBase::loadXrefInfo(): instantiates with 'stock' package guid
- list_assemblies.php: gallery_id param, show_empty default for flat list
- edit_assembly.php: STOCKCOMPONENT_CONTENT_TYPE_GUID → string literal
- ImportSimpleComponent: SCREF lookup fixed (xkey not xkey_ext), #SUP row
  now carries PN/price/URL directly; #PN #PR #URL separate rows removed
- ImportKitlockerAssemblies, load_kitlocker_assemblies, load_component_list:
  new importers for KitlockerAssemblies.csv (A/C split) and Component List.csv
- print_bom.php + print_bom.tpl: read-only printable BOM (p_stock_view only)
  with auto window.print() on load
- component_order.tpl: print icon (floaticon), position number for print,
  hidden-print on form controls
- list_stock.tpl: print icon
- view_assembly.tpl: print icon → print_bom.php; permission gates tightened
- ipackage duplicate attributes removed from templates
