Add API tokens management, docs & UI

Introduce full API token support: add a Prisma migration to create api_tokens table and indexes; add types, constants and a generateApiToken utility (hashed token + prefix). Update admin and user token routes to use the generator, enforce per-user active token caps, and integrate rate-limit checks. Add an interactive API docs page with TokenInput, EndpointCard and ResponseViewer components, plus a protected page route. Improve confirmation UX with an accessible ConfirmDialog (focus trap, Escape to close, animations) and wire confirm flows into admin/profile token sections; also update ConfirmModal to accept node messages. Add dialog CSS animations and enhance clipboard error handling. Update related middleware, utils and tests to reflect changes.
