feat: i18n on Filament admin sidebar — 54 resources/pages translated

User screenshots showed the tenant admin panel (Filament) had sidebar
labels stuck in Romanian even when switching to Russian: 'Cereri',
'Calendar vizual', 'Atelierul meu', 'KPI mecanici', 'Fișe lucru',
'Norme-ore', 'Tehnicieni', 'Șabloane servicii', 'Depozite', 'Scaner',
'Depozit', 'VIN-căutare', 'Furnizori', 'Achiziții', 'Procentaj',
'Coeficienți preț', plus all group headers.

Root cause: every Filament Resource and Page had static properties
'protected static ?string $navigationLabel = "Fișe lucru"' — string
literals baked into class definitions. Static properties don't run
through the translation layer.

Fix in two parts:

1. New translation files with 52 label keys + 12 group keys:
   - lang/ro/nav.php — Romanian (identity)
   - lang/ru/nav.php — full Russian translations (Заказ-наряды,
     Автомобили, Клиенты, Календарь, Моя мастерская, Механики KPI,
     Настройки, etc.)
   - lang/en/nav.php — English translations (Work orders, Vehicles,
     Clients, Calendar, My workshop, Mechanic KPI, Settings, etc.)

   Keyed by the Romanian original so lookups map 1:1 —
   'nav.label.Fișe lucru' returns 'Заказ-наряды' in RU, 'Work orders'
   in EN, 'Fișe lucru' in RO.

2. Python transformer converted 54 files:
   - 33 Filament Tenant Resources
   - 15 Filament Tenant Pages
   - 4 Filament Central Resources
   - 1 Filament Central Page
   - 1 Widget

   Each 'protected static ?string $navigationLabel = "X";' became
   'public static function getNavigationLabel(): string { return
   __("nav.label.X"); }'. Same treatment for $navigationGroup.

Cleanup: 6 resources already had manually-added getNavigationLabel
methods from an earlier partial effort — those used flat JSON keys
(__("Cereri")) that never resolved. Deduped so only the nav.label.*
version remains.

Untouched (intentional):
- $modelLabel / $pluralModelLabel (used in breadcrumbs and headings —
  still hardcoded, next tier of work)
- Section titles, column headers, form field labels (medium priority)
- $navigationSort (numeric, no translation needed)
- $navigationIcon (icon reference)

Suite: 306 passed (853 assertions). Unchanged.
