* Allow Emails::RemoveOldEmailsWorker to run longer
We set the SQL statement timeout based on the STATEMENT_TIMEOUT
environment variable (defaulting to 2.5 seconds in production), but not
all SQL queries are created equal. Since some may take longer out of
necessity, this PR introduces a `Model.with_statement_timeout` method
that allows you to change the SQL statement timeout only for a given
block.
* EmailMessage doesn't inherit ApplicationRecord
It inherits from `Ahoy::Message`, which inherits directly from
`ActiveRecord::Base`.
