Subject: [PATCH 01/18] feat(authz): add role assignation wizard scope
 selection step

Add scope selection step (step 2) to the role assignation wizard, including
ScopeList, ScopeFilterBar, useScopeListData, and useScopePermissions. Migrate
useScopes to infinite query, fix useOrgs data extraction, add missing
userRoles cache invalidation on role assignment, and align all tests with
the updated hook shapes.
