refactor: remove context parameter and unused deps from InstanceRepository (#7466)

* Refactor: Remove context parameter from InstanceRepository

The `Context` parameter was unused in the `InstanceRepository` constructor and has been removed. This simplifies the class and its instantiation.

* Refactor: remove unused imports in InstanceRepository

The `Context` and `R` imports were not used in `InstanceRepository.kt` and have been removed.
