Access to management features based on user roles

We currently have four different roles that enable station management in our B2B portal:

ADMIN : Full access to the platform: management of tariffs, user rights, stations as well as invoice review

OPERATOR : Manages stations like an ADMIN but without access to tariffs and user‑rights.

ACCESS MANAGER : Can view all stations and transactions – without financial data – and manage station access rights.

VIEWER : Read‑only access to all station and transaction data, no ability to act.
