* worker: log the balance move stage through a constant format string
Go 1.26's printf analyzer now follows printf wrappers reached through an
interface, so passing the stage straight to Logger.Info is a vet failure.
* s3api: bracket the IPv6 host in the signature test URL
A bare IPv6 literal is legal in a Host header but never in a URL. Go 1.26
stopped parsing it leniently, so carry the two forms separately and set
r.Host to the value the client would actually have signed.
* mini: bracket IPv6 addresses in the readiness probe URLs
An IPv6-only host hands mini a bare literal, and %s:%d pasted it into a URL
unbracketed. Under Go 1.26 that URL no longer parses, so waiting for the
admin server never succeeds and mini refuses to start.
