fix(marketplace): filter own products by company_id from JWT

- Add companyId field to AuthUser interface in AuthContext
- Extract company_id from JWT payload in Login.tsx
- Use user.companyId to filter products where seller_id matches
- This properly excludes own store products using UUID comparison
