feat: opt-in sync of deletes and restores from web to Android (beta timeline) (#20473)

* feature(mobile, beta, Android): handle remote asset trash/restore events and rescan media
- Handle move to trash and restore from trash for remote assets on Android
- Trigger MediaScannerConnection to rescan affected media files

* feature(mobile, beta, Android): fix rescan

* fix imports

* fix checking conditions

* refactor naming

* fix line breaks

* refactor code
rollback changes in BackgroundServicePlugin

* refactor code (use separate TrashService)

* refactor code

* parallelize restoreFromTrash calls with Future.wait
format trash.provider.dart

* try to re-format trash.provider.dart

* re-format trash.provider.dart

* rename TrashService to TrashSyncService to avoid duplicated names
revert changes in original trash.provider.dart

* refactor code (minor nitpicks)

* process restoreFromTrash sequentially instead of Future.wait

* group local assets by checksum before moving to trash
delete LocalAssetEntity records when moved to trash
refactor code

* fix format

* use checksum for asset restoration
refactro code

* fix format

* sync trash only for backup-selected assets

* feat(db): add local_trashed_asset table and integrate with restoration flow
- Add new `local_trashed_asset` table to store metadata of trashed assets
- Save trashed asset info into `local_trashed_asset` before deletion
- Use `local_trashed_asset` as source for asset restoration
- Implement file restoration by `mediaId`

* resolve merge conflicts

* fix index creating on migration

* 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.

* resolve merge conflicts
use updated approach for calculating checksums

* use CurrentPlatform instead _platform
fix mocks

* revert redundant changes

* Include trashed items in getMediaChanges
Process trashed items delta during incremental sync

* fix merge conflicts

* fix format

* trashed_local_asset table mirror of local_asset table structure
trashed_local_asset<->local_asset transfer data on move to trash or restore
refactor code

* refactor and format code

* refactor TrashedAsset model
fix missed data transfering

* refactor code
remove unused model

* fix label

* fix merge conflicts

* optimize, refactor code
remove redundant code and checking
getTrashedAssetsForAlbum for iOS
tests for hash trashed assets

* format code

* fix migration
fix tests

* fix generated file

* reuse exist checksums on trash data update
handle restoration errors
fix import

* format code

* sync_stream.service depend on repos
refactor assets restoration
update dependencies in tests

* remove trashed asset model
remove trash_sync.service

remove unused code

* optimize sync trashed assets call in full sync mode
refactor code

* fix format

* remove albumIds from getTrashedAssets params
fix upsert in trashed local asset repo
refactor code

* fix getTrashedAssets params

* fix(trash-sync): clean up NativeSyncApiImplBase and correct applyDelta

* refactor(trash-sync): optimize performance and fix minor issues

* refactor(trash-sync): add missed index

* feat(trash-sync): remove sinceLastCheckpoint param from getTrashedAssets

* fix(trash-sync): fix target table

* fix(trash-sync): remove unused extension

* fix(trash-sync): remove unused code

* fix(trash-sync): refactor code

* fix(trash-sync): reformat file

* fix(trash_sync): refactor code

* fix(trash_sync): improve moving to trash

* refactor(trash_sync): integrate MANAGE_MEDIA permission request into login flow and advanced settings

* refactor(trash_sync): add additional checking for experimental trash sync flag and MANAGE_MEDIA permission.

* refactor(trash_sync): resolve merge conflicts

* refactor(trash_sync): fix format

* resolve merge conflicts
add await for alert dialog
add missed request

* refactor(trash_sync): rework MANAGE_MEDIA info widget
show rationale text in permission request alert dialog
refactor setting getter

* fix(trash_sync): restore missing text values

* fix(trash_sync): format file

* fix(trash_sync): check backup enabled and remove remote asset existence check

* fix(trash_sync): remove checking backup enabled
test(trash_sync): cover sync-stream trash/restore paths and dedupe mocks

* test(trash_sync): cover trash/restore flows for local_sync_service

* chore(e2e): restore test-assets submodule pointer
