add setup wizard, lockdown, team tasks, embed builder; fix admin dashboard

Four new independent features: /setup (guided onboarding wizard for
module/channel/automod-strength config), /lockdown (raid protection with
per-channel permission snapshot/restore and join-kick), /task (staff task
tracker with status buttons + dashboard view), /embed create (modal-driven
embed builder with optional link button). Also fixes the Admin dashboard,
which always showed "-" because loadAdminData() double-wrapped the overview
response and discarded activity data, plus mismatched field names against
adminService's actual shape (guildCount/activeGuilds24/uptimeMs).
