feat(i18n): convert 38 hardcoded static labels + safe blade wrap + 226 keys

- Convert all remaining static \$modelLabel/\$pluralModelLabel to getter
  methods with __() (AppointmentResource, WorkOrderResource, MasterResource,
  ServiceTemplateResource, LaborResource, and 33 others)
- Safe blade wrap v2 (37 files, 201 wraps): fixed the regex to not match
  `->`, `=>`, `!<` — previous aggressive pass broke @if directives
- Bulk-translate lowercase model-label keys (programări, fișe lucru,
  tehnicieni, șabloane servicii, norme-ore, etc.) — these were the RO
  strings appearing in page titles/breadcrumbs
- Add human RU/EN for mechanic-kpi (Mecanic/Lucrări/Norma ore/etc.)
  and calendar-board words

Tests 306 green. Blade compiles cleanly.
