Refactor DbRepository methods for clarity and extensibility

Updated methods in the `DbRepository` class to be virtual, allowing for overriding in derived classes. Renamed parameters from `dto` to `entity` and `dtos` to `entities` for improved clarity. All methods still throw `NotImplementedException` as implementations are pending.
