refactor: update generated PokeAPI client with camelCase and PascalCase naming conventions

This commit introduces several improvements to the generated PokeAPI client:
- Converted function names to camelCase (e.g., `ability_list` → `abilityList`)
- Updated type names to PascalCase (e.g., `ability_listResponse200` → `AbilityListResponse200`)
- Modified client generator to support dynamic naming transformations
- Updated React Query and schema generators to use new naming conventions
- Added utility functions for camelCase and PascalCase conversions
