[native] Download and apply logs

Summary:
Update the code to also apply logs. Besides the actual download_and_apply_logs function that handles downloading, decrypting and applying logs there are a few small changes that I merged with this diff. If this makes it hard to review, feel free to request changes.

• Call triggerBackupFileUpload after C++ created a log file, so that it is uploaded
• Change SQLiteQueryExecutor code so that it starts numbering from 1 instead of 0 (the networking client expects that it starts with 1)
• Also store the encryption key for backup logs in UserKeys
• restoreFromBackupLog has been updated to call resolveUnitFuture/rejectFuture after log is applied so that execution returns to the rust code

Depends on D10987

Test Plan:

• Change StaffUtils::isStaffRelease to true
• Enabled uploading backups
• Made a new draft ("compaction draft")
• Created a new compaction and waited for it to be successfuly uploaded
• Created a new draft ("log draft")
• Logged out
• Logged in, into the same account
• Checked that the drafts weren't there
• Restored from backup
• Restarted the app so redux would refresh
• Checked that both drafts were restored
