Introduced entity configurations in `RecDbContext` for `Connection`, `Endpoint`, `EndpointAuth`, `EndpointParam`, `OutRes`, `Profile`, `ProfileView`, `RecAction`, and `RecActionView`. Mapped entities to corresponding tables or views with column configurations. Added relationships: - `Profile` to `Actions` (one-to-many). - `RecAction` to `OutRes` (one-to-one with cascade delete). Suppressed CS0618 warnings in `OnModelCreating` to handle obsolete members.
