The feature

When using the Immich mobile app, deleting photos from the server also deletes the corresponding local photos on the device. In some cases, this may not be the intended behavior for users. I would like to request an option that allows users to delete photos from the server while retaining the local copies on their devices.

Expected Behavior

When users delete photos from the server, the app should only remove them from the server without affecting the local copies on the device.
This could be implemented as a setting option or a confirmation dialog (e.g., "Do you also want to delete the local photo?") during the delete operation.
Current Behavior
Currently, when a photo is deleted from the server, the corresponding local photo is also deleted from the device.

Motivation

To prevent accidental loss of local photos.
To provide users with greater flexibility in managing their photos, meeting more diverse use cases.
Proposed Solution

Add a global setting that allows users to choose whether deleting server photos should affect local copies.
Alternatively, display a confirmation dialog during each delete operation, letting users decide whether to also delete the local photo.
