docs: simplify CLAUDE.md, update README with accurate business rules

CLAUDE.md reduced from 214 to 60 lines — moved architecture, API endpoints,
and detailed docs to README. Kept only AI-critical rules (TeamCreate, import
flow gotchas, partner/pricing logic).

README updated: added CANCELLED status, dual pricing policy, discount VAT
splitting, stale error recovery, accurate partner/address logic, settings
page references. Removed outdated Status Implementare section.

 ## Fluxul de Import
 
 ```
-1. gomag_client.py descarca comenzi GoMag API → JSON files
-2. order_reader.py parseaza JSON-urile
-3. validation_service.py valideaza SKU-uri contra ARTICOLE_TERTI + NOM_ARTICOLE
-4. import_service.py creeaza/cauta partener in Oracle (shipping person = facturare)
-5. PACK_IMPORT_COMENZI.importa_comanda_web() insereaza comanda in ROA
-6. Rezultate salvate in SQLite (orders, sync_run_orders, order_items)
+1. gomag_client.py descarca comenzi GoMag API → JSON files (paginat)
+2. order_reader.py parseaza JSON-urile, sorteaza cronologic (cele mai vechi primele)
+3. Comenzi anulate (GoMag statusId=7) → separate, sterse din Oracle daca nu au factura
+4. validation_service.py valideaza SKU-uri: ARTICOLE_TERTI (mapped) → NOM_ARTICOLE (direct) → missing
+5. Verificare existenta in Oracle (COMENZI by date range) → deja importate se sar
+6. Stale error recovery: comenzi ERROR reverificate in Oracle (crash recovery)
+7. Validare preturi + dual policy: articole rutate la id_pol_vanzare sau id_pol_productie
+8. import_service.py: cauta/creeaza partener → adrese → importa comanda in Oracle
+9. Invoice cache: verifica facturi + comenzi sterse din ROA
+10. Rezultate salvate in SQLite (orders, sync_run_orders, order_items)

@@ -180,17 +184,30 @@ gomag-vending/
 | `IMPORTED` | Importata nou in ROA in acest run |
 | `ALREADY_IMPORTED` | Existenta deja in Oracle, contorizata |

 **Regula upsert:** daca statusul existent este `IMPORTED`, nu se suprascrie cu `ALREADY_IMPORTED`.
 
 ### Reguli Business
-- **Persoana**: shipping name = persoana pe eticheta = beneficiarul facturii
-- **Adresa**: cand billing ≠ shipping → adresa shipping pentru ambele (facturare + livrare)
-- **SKU simplu**: gasit direct in NOM_ARTICOLE → nu se stocheaza in ARTICOLE_TERTI
-- **SKU cu repackaging**: un SKU → CODMAT cu cantitate diferita
-- **SKU set complex**: un SKU → multiple CODMAT-uri cu procente de pret
+
+**Parteneri & Adrese:**
+- Prioritate partener: daca exista **companie** in GoMag (billing.company_name) → firma (PJ, cod_fiscal + registru). Altfel → persoana fizica, cu **shipping name** ca nume partener
+- Adresa livrare: intotdeauna din GoMag shipping
+- Adresa facturare: daca shipping name ≠ billing name → adresa shipping pt ambele; daca aceeasi persoana → adresa billing din GoMag
+- Cautare partener in Oracle: cod_fiscal → denumire → create new (ID_UTIL = -3)
+
+**Articole & Mapari:**
+- SKU lookup: ARTICOLE_TERTI (mapped, activ=1) are prioritate fata de NOM_ARTICOLE (direct)
+- SKU simplu: gasit direct in NOM_ARTICOLE → nu se stocheaza in ARTICOLE_TERTI
+- SKU cu repackaging: un SKU → CODMAT cu cantitate diferita (`cantitate_roa`)
+- SKU set complex: un SKU → multiple CODMAT-uri cu `procent_pret` (trebuie sum = 100%)
+
+**Preturi & Discounturi:**
+- Dual policy: articolele sunt rutate la `id_pol_vanzare` sau `id_pol_productie` pe baza contului contabil (341/345 = productie)
+- Daca pretul lipseste in politica, se insereaza automat pret=0
+- Discount VAT splitting: daca `split_discount_vat=1`, discountul se repartizeaza proportional pe cotele TVA din comanda
