feat(purchase): implement PurchaseController with CRUD operations and request validation

Move Catalog endpoints under /api/tenants/{tenant:codigo} and derive tenant
context from the route instead of request payload fields.

- scope marcas, categorias, productos, and product-attributes by tenant
- enforce tenant ownership in catalog controllers
- remove tenant_codigo and tenant_code from Catalog request validation
- update product attribute tests to use tenant-scoped routes
