Add mail namespace with Stalwart backing stores (#538)

Stalwart needs a Postgres metadata store and an S3 blob store before it can be deployed into the new `mail` namespace. - add CNPG Cluster `stalwart-db` (db/owner `stalwart`, CNPG-minted `stalwart-db-app` creds) with barman backups to a dedicated `cnpg-mail` bucket and a nightly ScheduledBackup - add cephrgw Bucket `stalwart-blobs` with an owner user writing RW keys to `stalwart-blobs-s3` - add the au-syd1 overlay, platform ApplicationSet path and project destination Reviewed-on: #538 Co-authored-by: unkin-agent <unkin-agent@unkin.net> Co-committed-by: unkin-agent <unkin-agent@unkin.net>
