Yurii Rashkovskii 855e08d22d Problem: ActionMailbox uses default ActiveStorage service
This is imperfect in situations when a separation
between regular files (such as uploads) and emails
is necessary (for the purposes of regulatory compliance,
proper compartmentalization, etc.)

Solution: allow configuring ActionMailbox's storage service
