refactor: мигрировать на новую систему документов поступления

Удалена старая одноэтапная система incoming и оставлена только новая
двухэтапная система IncomingDocument (черновик → проведение).

Изменения:
- URL структура изменена с /incoming-documents/ на /incoming/
- URL names: incoming-document-* → incoming-*
- Удалены старые views, forms, templates для Incoming/IncomingBatch
- Обновлена навигация и все ссылки в шаблонах
- Модели IncomingBatch/Incoming сохранены как внутренняя архитектура

Удалено ~1590 строк кода:
- inventory/views/incoming.py (389 строк)
- inventory/forms.py (206 строк старых форм)
- inventory/admin.py (56 строк)
- 4 шаблона incoming/*.html (895 строк)

Обновлено:
- inventory/urls.py - новая URL структура
- inventory/views/incoming_document.py - обновлены redirects
- Все шаблоны с ссылками на incoming
