- Migration: create `units` table + nullable unit_id FK on
parts / wo_parts / purchase_items / labor_parts. Seeds ~11 standard
units (buc/set/l/ml/kg/g/m/cm/m²/oră/pack) for every existing
tenant and backfills unit_id by matching the legacy string `unit`
column. Keeps `unit` string as fallback so old code paths keep
rendering.
- Unit model: label(locale), forSelect(locale), labelFor(id, code)
helpers. All 4 owner models get unitModel() relation + unitLabel()
accessor.
- UnitResource under Depozit group with Filament UI: code, sort,
is_active + separate name_ro/name_ru/name_en fields.
- Filament forms/tables updated: Part / PurchaseItem / LaborPart /
WorkOrderPart now use Select('unit_id')->options(Unit::forSelect())
for input and TextColumn->getStateUsing(unitLabel()) for display.
Selecting a part auto-fills unit_id when the source has one.
- +10 translations for the new resource + defaults; nav.label
'Unități de măsură' added to all 3 lang files.
All 306 tests pass.
