feat(test): Add comprehensive unit tests for all Rails models

- Create detailed unit tests for Party, TicketType, Ticket, User, and ApplicationRecord models
- Add fixture files for all models with valid test data
- Fix enum syntax in Party model for Rails 8 compatibility
- Add 60 total model tests covering validations, associations, and business logic
- Ensure all tests pass successfully

This provides full test coverage for the application's data models.
