GET /v1/users/{id}/memberships answers 'which tenants does this JWT
subject belong to, with which org_roles and entitlements' (ratified
auth design, model B2). Keycloak supplies user->tenant links and roles
via the Adapter (attribute projection until the realm migrates to
Organizations); registered tenants override status/plan/products from
registry tables.
New internal/authn verifies Keycloak bearer tokens (OIDC discovery +
JWKS, audience AUTH_EXPECTED_AUDIENCE, default tenant-registry). With
AUTH_ENABLED=true all routes except /healthz + /readyz require a token
and the server refuses to start if the verifier cannot initialize;
false (dev default) keeps the API open. Completes the M5.2-deferred
org_roles lookup and replaces the 'M4.3 adds JWT validation' TODO in
the spec.

// Package keycloak adapts the Keycloak Admin API to the tenant-registry's
|
|
// language of "tenants" and "IT_ADMIN invites".
|
|
//
|
|
// The Adapter interface is the seam: tenant-registry handlers depend on
|
|
// it, never on the concrete HTTP client. Tests use Mock; production uses
|
|
// HTTPAdapter against the real KC at the configured base URL.

// Required Keycloak features (verified against KC 26):
|
|
// - Organizations feature enabled in the realm (organizationsEnabled: true)
|
|
// - Realm roles: BREAKPILOT_ADMIN, SUPPORT_ENGINEER, SALES_REP
|
|
// - Group `/IT_ADMIN` (used as the org_role marker for invited users)

|
|
// All errors are wrapped with %w so callers can errors.Is them against
