Administrator tools - Frontend

## Story Statement As a platform administrator, I want secure authentication, role-based authorization, and admin-controlled user provisioning so that access is consistently enforced and governed for all role types. ## Business Value - Strengthens security and governance of role access. - Reduces operational risk from misconfigured permissions. - Improves compliance readiness through controlled access.

## Story Statement As a metadata manager, I want configurable metadata taxonomies (domains and values) and multi-level metadata assignment so that taxonomies can evolve and be applied consistently across recipe, topic, and element levels. ## Business Value - Improves content filtering and precision in delivery channels. - Supports scalable taxonomy management across products. - Increases downstream automation through richer metadata context.
