Backend
-------
New REST surface at /api/admin/users/:oid/scopes guarded by
@RequireAdmin (Portal.Admin privilege per ADR-0020). Three endpoints:
GET list a user's scopes with the linked User + Person info
(no audit on reads)
POST grant a new scope - validates kind via SCOPE_KINDS catalogue,
validates value against Structure.code / Delegation.code /
Region.code for value-bearing kinds, rejects non-empty values
for valueless kinds, translates Prisma P2002 to a 400 with
"already granted"; emits admin.scope_granted (blocking
audit per ADR-0013)
DELETE :scopeId 404-protected against cross-user revocation;
emits admin.scope_revoked with the resolved tuple at the
moment of deletion
Two new audit types (AdminScopeGrantedInput / AdminScopeRevokedInput)
+ two AuditWriter methods. subject = "user:<oid>" so an auditor
pivots on the target of the change.
UserScope rows created here use source = "admin-ui" (distinct from
seed-written "seed" and Person-only "self-signin").
Frontend
--------
New Angular page at /admin/users/:oid/scopes (lazy-loaded). Lists
current scopes in a table with per-row Revoke buttons; "Grant a new
scope" form with kind dropdown + conditional value input + optional
expiresAt datetime. Friendly error mapping: 403 -> "no admin access",
404 -> "User not found, has this persona ever signed in or been
seeded?", server messages forwarded.
A11y per ADR-0016: aria-labelledby on form sections, role="status"
/ aria-live="polite" for load/error feedback, role="alert" for
submit errors, min-height 44px on every input/button, aria-label
on the Manage-scopes link carrying the user's displayName,
conditional aria-required + aria-describedby on the value input.
"Manage scopes" link added to each row of the existing /admin/users
list, navigating to the new page via the user's Entra oid.
Local: drift gate 4/24/7/3 clean; portal-bff lint 0 err; portal-admin
lint 0 err; both test suites green (portal-admin 71 tests, +8 for
user-scopes).
Closes the ADR-0026 trilogy alongside PRs #232 and #233. ADR-0025's
@RequireScope stack is now end-to-end live for the test tenant.
