feat: add Pavao and Irrecusable proposal models and services

- Introduced models for Pavao and Irrecusable proposals and their respective products and units.
- Implemented ProposalPricingService for handling CRUD operations and cloning for proposal pricing.
- Updated ClassPackageService and ClassPackageUnitService to integrate new proposal functionalities.
- Created migrations for the new proposal and product tables.
- Added validation tests for proposal pricing sections to ensure correct data handling.
