refactor(inventory): remove individual writeoff views and templates, shift to document-based writeoffs

Browse Source 
- Remove WriteOffForm from forms.py and add comment directing to WriteOffDocumentForm
- Update navigation templates to remove writeoff links and sections
- Add 'Сумма' column to sale list with multiplication filter
- Delete writeoff-related templates (list, form, confirm delete)
- Add 'multiply' filter to inventory_filters.py for calculations
- Comment out writeoff URLs in urls.py, keeping WriteOff model for automatic creation
- Remove WriteOff views from __init__.py and delete writeoff.py view file

This change simplifies writeoff management by removing direct individual writeoff operations and enforcing use of WriteOffDocument for all writeoffs, with WriteOff records created automatically upon document processing.
