## Description
Truncates long contact names in `ContactInboxWithContactBuilder` before
persisting them, so inbound IMAP sender display names over the
`contacts.name` 255-character limit no longer raise
`ActiveRecord::RecordInvalid` from `Inboxes::FetchImapEmailsJob`. This
keeps email ingestion moving while preserving the existing contact name
length constraint.
