rework trashed assets handling

- add new table trashed_local_asset
- mirror trashed assets data in trashed_local_asset.
- compute checksums for assets trashed out-of-app.
- restore assets present in trashed_local_asset and non-trashed in remote_asset.
- simplify moving-to-trash logic based on remote_asset events.
