admin-panel: drop six more redundant add entries from the sidebar

Each now has an add button at the top of its own list page, so the nav
entry duplicated it:
  - 'افزودن دسته بندی'          (/category/add)
  - 'وارد کردن سند مالی مشتری'  (/add/findoc)
  - 'تعریف تخفیف  تک'           (/major/promotion/tak/add)
  - 'تعریف تخفیف  عمده'         (/major/promotion/add)
  - 'افزودن فاکتور'             (/invoice/add)
  - 'افزودن شهر'                (/city/create)

Only adminMenu is touched; all six routes still exist and still work as a
direct-link fallback. Parent submenus keep their remaining children
('تخفیف اتوماتیک' and 'لیست تخفیفات ' both still sit under 'تخفیفات', for
instance).

Verified in a real browser: menu items 26 -> 20, none of the six labels
render, all five parent submenus (دسته بندی ها، اسناد مالی، تخفیفات، فاکتور
انتقال، شهر ها) still present with their list children, icons unchanged at
16, no console errors. Committed dist/ artifact rebuilt to match.
