v0.43.0: rebuilt storage management (guided init/attach/eject on agent disk model)

Controller-only UI/orchestration over the agent's disk endpoints + StoragePath
registry. New: storage overview (data_bearing badges), guided init (format ->
resolve fs UUID -> assign -> register; data-bearing REFUSAL surfaces the
felhom-opsign command, no force-format), guided attach, eject (+deregister,
dependent-guest warning). agentapi: DiskInfo.DurableID/FSUUID + FormatResult.
PendingOp (parsed from the 403). Honest buttons (migrate disabled, no 404s).
Phase 3: removed dead CrossDrive blocks in deploy.html/backups.html.
