feat(admin): sessions, staff auth and adminctl

One Redis session store and one cookie for all three identities. Staff login returns the same error for every failure mode and spends a bcrypt comparison against a dummy hash when no user exists, so neither the message nor the timing confirms which addresses have accounts. Staff users are created only by adminctl. There is no signup endpoint: a licensing authority that can be joined over the internet is not one. Pins gin and go-redis to the versions server/ already uses rather than the latest tidy would pick. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
