CW-875 BackupServiceV3 (#2064)

* implement v3 backup system

- Add new BackupServiceV3 with chunked backup support and checksums
- Implement json-based metadata in backup system
- Instead of binary file export a .zip file that user can open and
see that it is a cake backup
(should also prevent 3rd party software from corrupting binary
data inside of the file, in case it doesn't checksum will fail,
and user will know for sure that backup got corrupted)
- Update flutter to 3.27.4 to use archive ^4.x.x (it offers in memory
archive operations)

* fix wallets not getting restored properly

* prevent out of memory errors on files that are way too big during restore

* Update lib/view_model/backup_view_model.dart [skip ci]

* Update lib/core/backup_service.dart [skip ci]

* Update lib/core/backup_service.dart
