Implement trial period and access restrictions

Implement a 30-day trial period for new users. After the trial, restrict the ability to add new transactions if no payment is detected. Use `usuarios.created_at` for the registration date and consider a payment active if a record exists in `pagamentos_mercadopago` with status "approved".
