fix(ios): translate the table page range

[datlechin]

Summary

The page range under a table on iPhone and iPad ("1-100 of 3503") was English in every language. DataBrowserViewModel.paginationLabel built it with plain string interpolation and DataBrowserView shows it through Text(String), which never looks anything up. It turned up in the App Store screenshots, where it was the only English text on the Vietnamese, Korean and Chinese screens.

Change

• pageRangeLabel(start:end:total:bundle:) formats String(localized: "%1$lld-%2$lld of %3$lld"), following the house rule of never interpolating inside String(localized:). The range without a total is digits only and stays as it was.
• The key is added to the iOS catalog, translated into Vietnamese, Korean, Simplified and Traditional Chinese in the same shape as the existing %lld of %lld row counter.

Tests

• New pageRangeLabelIsLocalized checks the English output, and the Vietnamese output read from the app's compiled vi.lproj.
• Full iOS test target on the iPhone 18 Pro simulator: 667 passed, 0 failed.
• localization.py --target ios verify: ok. SwiftLint strict on both files: clean.
