feat(mobile): show local assets (#905)

* introduce Asset as composition of AssetResponseDTO and AssetEntity

* filter out duplicate assets (that are both local and remote, take only remote for now)

* only allow remote images to be added to albums

* introduce ImmichImage to render Asset using local or remote data

* optimized deletion of local assets

* local video file playback

* allow multiple methods to wait on background service finished

* skip local assets when adding to album from home screen

* fix and optimize delete

* show gray box placeholder for local assets

* add comments

* fix bug: duplicate assets in state after onNewAssetUploaded
