feat(equipment-view): Integrate OWS into Maintenance menu with Equipment-centric views

- Extended maintenance.equipment model with Related fields to ows.machine
  - ows_machine_id: One2many inverse relation
  - ows_category: Related to machine category (editable, stored)
  - ows_area_id: Related to machine area (editable, stored)
  - ows_product_ids: Related One2many for usage products
  - ows_training_ids: Related One2many for training products

- Equipment Form View Extensions:
  - Added ows_area_id and ows_category after location field
  - New 'Offene Werkstatt (Hobbyhimmel)' notebook page with:
    - Security section (category icon, category, area)
    - Usage products section (Nutzungsprodukte)
    - Training products section (Einweisungsprodukte)
  - Page visibility controlled by ows_machine_id existence

- Equipment List/Search View Extensions:
  - Added ows_category_icon and ows_area_id columns
  - Added OWS search fields (area, category)
  - Added category filters (green/yellow/red)
  - Added OWS grouping options (by area, by category)

- Menu Structure Migration:
  - Removed standalone 'Ausrüstung' top-level menu
  - Integrated all OWS config into Maintenance → Configuration:
    - Bereiche (Areas)
    - Zuordnungen (Assignments) container
      - Nutzungsprodukte (Usage Products)
      - Einweisungsprodukte (Training Products)

- Created simplified tree views for Equipment context:
  - view_ows_machine_product_tree_simple (no machine_id column)
  - view_ows_machine_training_tree_simple (no machine_id column)

- Freed location field from automatic area synchronization:
  - Removed area → location mapping in create()/write()
  - location now available for detailed physical location info
  - ows_area_id provides workspace area assignment

BREAKING CHANGE: Standalone OWS menu removed, all features now in Maintenance app
UX IMPROVEMENT: Single Equipment view shows all data, no split views needed
