Remove duplicates with shared albums

[SkypLabs]

Describe the feature

As of now, the Remove duplicates feature does not take into account items shared with us but only items owned by ourselves.

I would like to be able to automatically detect duplicates including from albums shared with me. This would be an awesome feature to consolidate albums with others.

As a concrete use case, friends and myself are uploading common memories to shared albums on Ente. We often encounter duplicates due to pictures having been shared by other canals (e.g. Signal) before starting to use Ente.
