Refactor: replace RecActionDto with RecActionViewDto

Standardize usage of RecActionViewDto across the codebase:
- Update pipeline behaviors, mapping profiles, and commands to use RecActionViewDto.
- Remove RecActionDto and introduce RecActionViewDto with equivalent properties and methods.
- Adjust query handlers and related interfaces to work with RecActionViewDto.
This clarifies DTO usage and aligns the model with domain intent.
