i18n(users): translate 'status' badge column + relabel Locale → Язык / Language

Status column showed raw DB enum values (active/inactive/blocked) with
no formatStateUsing → readers saw 'active' instead of the translated
'Активный / Активно' visible in the Select. Added formatStateUsing with
a match() that returns the appropriate __() key.

Locale header re-translated to 'Язык' (RU) / 'Language' (EN) since
'Локаль' is unusual for end users.
