fix: use PlatformSettings for pagination in Letzshop page

- Load rows per page from PlatformSettings in init()
- Apply setting to ordersLimit, exceptionsLimit, productsLimit, jobsPagination
- Replace alert() with Utils.showToast() for error display
- Improve viewJobErrors to show errors in modal instead of alert
- Update architecture validator to catch non-standard pagination patterns
  (jobsPagination, ordersLimit, etc.)
