fix(ui): act-as strip no longer covers headers; customer type and slider permission

- apps: the fixed «در حال مشاهده به‌عنوان» strip (38px) sat over the fixed page
  headers, which still sat at top: 0 (the old 30px body padding was shorter than
  the strip too). The strip's height is now one variable, --aab-h, that the
  fixed headers (PageBar, home, dashboard, toasts) use as their top.
- admin: the customer form offers only «مغازه دار اپلیکیشن» to anyone but the
  super admin; bankers and walk-in shopkeepers are listed by super-admin-only
  endpoints, so ordinary admins lost the customers they created under them.
- admin: the mobile slider rid (custom.config.statics.slider) was only under the
  «سفارشی» branch, which the permission screen hides outside level 104. Same rid,
  now listed under «مدیریت ثابت ها». Display only: the slider routes are still
  gated by config.statics.

Rebuilds admin-panel, user-app and user-app-v2 dist.
