**Cleanup behavior:** A background sync runs every 15 minutes to reconcile the S3 bucket (or configured prefix) with
the server's message database. Objects whose keys match attachment file IDs that are no longer referenced in the database
(and are older than 1 hour) are automatically deleted. This also cleans up incomplete S3 multipart uploads that were
abandoned due to interrupted or failed attachment uploads.
Please also refer to the [rate limiting](#rate-limiting) settings below, specifically `visitor-attachment-total-size-limit`
and `visitor-attachment-daily-bandwidth-limit`. Setting these conservatively is necessary to avoid abuse.
