feat: melhorias no boletim, duplicação de provas e cadeado de retentativa

 12. **Messages Automation**: Preventive reminders and overdue settings MUST be managed within their respective template modals (contextual logic), with independent manual triggers for each phase (Overdue vs. Upcoming).
 13. **Grading & Evaluation Standards**: Assessments are categorized as `exam` (violet/violet labels) or `activity` (sky/blue labels). The report card (Boletim) MUST support multiple evaluations per period, showing the individual breakdown (name and value). The module MUST be named **"Atividades e Provas"** for clarity.
 14. **Asaas Safety**: All financial generation forms MUST implement a loading state (`isCreating`) to disable submit buttons and prevent duplicate charges.
-15. **Retake Policy**: Students ARE allowed to retake activities and exams. The system MUST delete the previous submission and overwrite the grade in `school_data.json` to ensure only the latest attempt is valid.
+15. **Retake Policy**: Students ARE allowed to retake activities and exams. The system MUST implement a "Lock" (Cadeado) logic: if locked, the retake button is hidden; if unlocked, the button is visible and the new submission overwrites the previous grade.
 16. **Financial Categories**: The system supports categories: `monthly` (Mensalidade), `registration` (Matrícula), `handout` (Apostila), and `others` (Outros). Automated forms must map references (Cursos -> monthly, Registration -> registration, Handout -> handout).
 17. **Modal Floating Principle**: All system modals must avoid backdrop-blur and background overlays. Use `bg-transparent` for the fixed container and `bg-white` (solid) for the modal box, ensuring contrast via large soft shadows (`shadow-2xl` or equivalent).
 18. **Automated Messaging (Cron Jobs)**: The system uses `node-cron` for independent message scheduling (Preventive vs. Overdue). Overdue logic MUST implement safety checks using `overdue_warnings_count` and `last_overdue_warning_at` to avoid spamming the student. Immediate webhook triggers for `PAYMENT_OVERDUE` are disabled in favor of scheduled routines.
 19. **Numerical Data Integrity**: When retrieving data from PostgreSQL `NUMERIC` or `DECIMAL` columns, values MUST be explicitly cast to `Number()` in the backend before being sent to the frontend to prevent crashes when using `.toFixed()` in React.
+20. **Exam Duplication**: The system supports cloning evaluations. Duplicated exams MUST default to `draft` status and include `(Cópia)` in the title to allow verification before deployment to new classes.
