Write unit tests for the Pydantic schemas in `backend/src/app/schemas/`. These are pure validation logic and can be tested without a database.

## Checklist

- [x] Test `CamelModel` base class (snake_case → camelCase alias generation)
- [x] Test run schemas — creation validation, required fields, optional fields, serialization
- [x] Test game schemas — validation rules, field constraints
- [x] Test encounter schemas — status enum validation, field dependencies
- [x] Test boss schemas — nested model validation
- [x] Test genlocke schemas — complex nested structures
- [x] Test evolution schemas — validation of evolution chain data
- [x] Test Pokemon create schema (types list, required fields)

## Notes

- Focus on: valid input acceptance, invalid input rejection, serialization output format
- The `CamelModel` base class does alias generation — verify both input (camelCase) and output (camelCase) work
- Test edge cases like empty strings, negative numbers, missing required fields
