stock: requisition system, movement BOM editor, autocomplete dropdowns

Requisitions:
- add_requisition.php: create REQN movements linked to assemblies or
  kitlocker components; Ordered date stored on REQN xref start_date
- ASSEMBLY xref group registered in schema (sort_order=1, template=assembly);
  ASSEMBLY item registered with multiple=1 for future multi-item reqns
- StockMovement::loadXrefInfo() enriches assembly group rows with
  linked_title/linked_desc from liberty_content
- view_xref_assembly_group/item templates: Assembly tab with qty, title
  link, type; Add item form on edit_movement for REQNs; hidden on I-direction
- view_movement/edit_movement: isReqn flag hides assembly tab and type
  selector on ORDER/TRANS; add another assembly from edit_movement

BOM editor:
- stockmovement/view_xref_bom_group: Add component links to new
  add_movement_component.php instead of generic liberty/add_xref.php
- add_movement_component.php/.tpl: movement-aware add component page;
  uses movement_lookup_inc, STOCKMOVEMENT_CONTENT_TYPE_GUID, sequential
  xorder, redirects back to edit_movement

Autocomplete dropdowns (replace <select> everywhere):
- add_requisition: hidden+text+dropdown widget; KLID in JSON for matching
- add_supplier: AJAX contact lookup replaces static supplier list
- list_stock: assembly selector replaced with autocomplete dropdown
- edit_movement: From field proper dropdown replacing datalist;
  Movement Type radio fixed (was reading non-existent mInfo[reference])
- view_xref_assembly_group: Add item inline form with same widget

Import:
- ImportKitlockerAssemblies: upsert xrefs on reload; KLID/KLSGL/KL3M
  now stored on both assemblies and components (not assembly-only)
- StockComponent::getList: kitlocker_only filter via EXISTS(KLID xref)

list_movements: Add Requisition icon alongside Add Movement in header
