Refactor Action class to RecAction

Replaced the `Action` class with a new `RecAction` class to represent the `VWREC_ACTION` database view. The `RecAction` class retains the same properties and annotations as the removed `Action` class, ensuring compatibility with the database schema.

Updated `RecDbContext` to use `RecAction`:
- Replaced `DbSet<Domain.Entities.Action>` with `DbSet<RecAction>`.
- Updated the `OnModelCreating` configuration to use `RecAction`.

This refactor improves clarity, aligns with naming conventions, and prepares the codebase for future changes.
