Faza 3.2: Service modules — Norme-ore, Tehnicieni, Fișe lucru

Schema:
- users + specialization, color, hourly_rate (pentru maistri)
- labors: catalog manopere standard cu category/ore/preț (RO+RU)
- work_orders: nr unique per tenant, status workflow (9 stări),
  pay_status (3 stări), client/vehicle/master/deal/appointment refs,
  complaint/diagnosis/recommendations, total auto-calculat
- wo_works: manopere per fișă, recalc auto la save/delete
- wo_parts: piese per fișă (free-text deocamdată), discount/total auto

Filament resources (group Service):
- LaborResource: CRUD + grupare pe categorie + filter active
- WorkOrderResource: form complex în 4 secțiuni (antet, diagnostic, plată)
  + 2 RelationManagers (Works, Parts)
- MasterResource: vedere User filtrată role=mechanic, edit specializare/
  culoare calendar/tarif oră

Conversie auto: la adaugare manoperă din catalog Labor,
form populează numele + ore + preț/oră derivat (price/hours).

Number generator pentru WO: format WO-{YY}-{NNNN} per tenant per an,
calculat în CreateWorkOrder via WorkOrder::generateNumber().

Seed extins:
- 3 mecanici (Vasile/Andrei/Nicolae) cu culori + specializări
- 10 manopere standard din prototipul AutoCRM.html
- 1 fișă demo (BMW X5 plăcuțe Brembo) cu 1 manoperă + 1 piesă, total auto
