Faza 3.3: Depozit — Furnizori + Catalog piese + Achiziții

Schema: - suppliers: name, contact, phone/email/website, pay_terms, delivery_days, rating (1-5), discount_pct, categories (JSON), is_active, notes - parts: name, article (UNIQUE per tenant), brand, category, qty/unit/min_qty, buy_price/sell_price, location (rack/bin), barcode, preferred_supplier_id, is_active. Index pe (company_id, category) și (company_id, is_active). - purchases: număr unique per tenant + an, supplier_id, status workflow (draft/ordered/received/cancelled), order/expected/received/paid_at, total - purchase_items: name, article, qty, unit, buy_price, total auto, received bool; link opțional la part_id - wo_parts + part_id: linkare opțională la catalog (alter migration) Modele cu logică: - Part::adjustStock($delta) — modifică qty cu validare ≥ 0 - Part::isLow() / isOut() helpers - Purchase::markReceived() — atomic: marchează items ca received + creste qty pe pieces din catalog (DB::transaction) - WorkOrderPart::updating event — la trecerea status='installed' decrementează stoc auto. La revenire (ex: storno) incrementează la loc. - PurchaseItem::saving — total = qty * buy_price; recalc parent total Filament resources (group Depozit): - SupplierResource: form 3 secțiuni, rating ★★★★★, TagsInput pentru categorii - PartResource: form 4 secțiuni, badge nav cu nr. piese sub stoc minim, filtre low_stock + out_of_stock, coloană qty colorată după stoc - PurchaseResource: form antet + RelationManager Items. Action 'Recepționează' care apelează markReceived() — un click = stoc actualizat WorkOrder PartsRelationManager updated: - Selector din catalog (Part::active) cu stoc afișat - Auto-fill name/article/brand/unit/buy_price/sell_price din piesa selectată - Helper text: la status='installed' se scade din stoc Widget low-stock: - TableWidget pe dashboard tenant, listează piesele cu qty <= min_qty - Span full, sortat după qty (cele mai critice sus) Seed: - 2 furnizori (AutoParts Moldova SRL ★5, Inter Cars Moldova ★4) - 5 piese demo: Ulei Shell, Filtru Mann, Plăcuțe Brembo, Antigel (qty=0!), Bujii NGK - 1 achiziție recepționată (P-26-0001) cu 2 articole linked la catalog Total Filament tenant routes: 63 (de la 31).
