feat(service-auto): phase 2 — comenzi browse, id_sucursala, cache, migrare SQL

Backend:
- GET /api/service-auto/comenzi cu paginare server-side, filtre dată/status
- ComandaRequest.id_sucursala (Optional) + FirmaItem.id_mama
- get_firme() expune id_mama din V_NOM_FIRME
- callproc SP_CREEAZA_COMANDA_PROTOTIP cu 7 argumente (+ p_id_sucursala)
- Cache TTL in-process: tip_deviz 24h, masini 5min

Frontend:
- ComenziBrowseView.vue — DataTable lazy + filtre + status badges
- ComandaNoua.vue — company store integration, idSucursala computed
- service-auto/stores/sharedStores.js (createCompaniesStore factory)
- HamburgerMenu: secțiune Service Auto (Comenzi + Comandă Nouă)
- router: /service-auto/comenzi

SQL:
- migrations/ff_2026_04_12_01_AUTO.sql — idempotent (COLUMNEXIST guard + CREATE OR REPLACE SP)
- onboarding_roa_web.sql — versioned, parametrizat cu :SCHEMA_NAME
- .claude/rules/oracle-migrations.md — convenție ff_YYYY_MM_DD_NN_MODULE.sql
