* web/templates/pgcreds.html: New Credentials card is now always rendered; Add Credentials toggle button reveals the create form (hidden by default). Shows a message when all system accounts already have credentials. Previously the card was hidden when UncredentialedAccounts was empty. * internal/ui/ui.go: added ActorName string field to PageData; added actorName(r) helper resolving username from JWT claims via DB lookup, returns empty string if unauthenticated. * internal/ui/handlers_*.go: all full-page PageData constructors now pass ActorName: u.actorName(r). * web/templates/base.html: nav bar renders actor username as a muted label before the Logout button when logged in. * web/static/style.css: added .nav-actor rule (muted grey, 0.85rem).
