Refactor to use RecActionView instead of RecAction

Replaced `RecAction` with `RecActionView` across the codebase to align with the `VWREC_ACTION` database view. Updated mappings, interfaces, and repository registrations accordingly.

- Updated `DtoMappingProfile` to map `RecActionView` to `RecActionDto`.
- Modified `IRecDbContext` to use `DbSet<RecActionView>`.
- Refactored `ReadRecActionQueryHandler` to use `IRepository<RecActionView>`.
- Removed the `RecAction` class entirely.
- Updated `DependencyInjection` to register `RecActionView`.
- Adjusted `RecDbContext` to replace `RecAction` with `RecActionView` and configure it as a keyless entity.
- Introduced the `RecActionView` class, mirroring the structure of the removed `RecAction` class, with nullable properties for schema flexibility.
