tower 0.60.1 / tower-ui 0.61.1 — auto-create + auto-name S3 buckets

Tenant pastes endpoint + region + access keys. Tower auto-derives
3 bucket names from slug (<slug>-backups, -templates, -audit) and
HeadBucket+MakeBucket each at credential-save time. UI removes the
3 bucket-name inputs entirely; shows what will be created instead.

Removes the 'go to MEGA dashboard, click new bucket × 3' toil.
One credential save = three buckets ready.
