Refactor GroupChannelEditScreen to handle its own GroupChannelEditViewModelFactory instantiation.

- Remove `viewModelFactory` parameter from `GroupChannelEditScreen` and internalize its creation using `LocalContext` and the provided `channel.cid`.
- Update `GroupChannelInfoScreen` to no longer pass a factory to `GroupChannelEditScreen`.
- Simplify `GroupChannelEditPlaceholder` by removing redundant factory initialization.
- Provide a default empty lambda for the `onDismiss` parameter in `GroupChannelEditScreen`.
