fix(i18n): auto-translate labels on Filament columns/fields/filters/actions

Root cause of untranslated table headers: Filament's HasLabel::getLabel()
auto-generates a label from the field name (e.g. `name` → "Name") but only
calls __() on it if you also invoke ->translateLabel(). Without that, the
auto-generated label always renders in English regardless of app locale.

Fix: configureUsing() in AppServiceProvider makes translateLabel() the
default for every Column, BaseFilter, Field, Action and BulkAction.

Then added 175 human RU/EN translations for Filament's auto-generated
keys (Name, Phone, Email, Status, Balance, Created at, Plate, Make,
Model, Year, VIN, Mileage, Owner, Client, Vehicle, Amount, Total, Qty,
Actions, Search, Filter, Export, Import, plus enums/relationships).

All 306 tests pass. Deploy will fix table headers on
Clients / Vehicles / Work orders / Payments / Purchases / Suppliers etc.
