feat(dashboard): add logs page, pagination, quick mapping modal, price pre-validation

- Add /logs page with per-order sync run details, filters (Toate/Importate/Fara Mapare/Erori)
- Add price pre-validation (validate_prices + ensure_prices) to prevent ORA-20000 on direct articles
- Add find_new_orders() to detect orders not yet in Oracle COMENZI
- Extend missing_skus table with order context (order_count, order_numbers, customers)
- Add server-side pagination on /api/validate/missing-skus and /missing-skus page
- Replace confusing "Skip"/"Err" with "Fara Mapare"/"Erori" terminology
- Add inline mapping modal on dashboard (replaces navigation to /mappings)
- Add 2-row stat cards: orders (Comenzi Noi/Ready/Importate/Fara Mapare/Erori) + articles
- Add ID_POL/ID_GESTIUNE/ID_SECTIE to config.py and .env
- Update .gitignore (venv, *.db, api/api/, logs/)
- 33/33 unit tests pass, E2E verified with Playwright
