Create a B2 cloud-backed snapshot (zero local disk, async).
Streams container data directly to Backblaze B2 via restic.
No local disk impact — billed separately at cost+5%.
Runs in background — returns immediately with status "creating".
Poll list_snapshots() to check when status becomes "completed".
Only available for VPS plans.
Requires: API key with write scope.
