fix(W3): remove incorrect 'Bearer' prefix in Authorization header

AList expects bare token (not 'Bearer <token>'). With 'Bearer' prefix,
all role/get calls returned non-data responses -> currentPaths degraded
to [] -> W3 kept re-applying same scopes every run (false toAdd) and
never detected expired scopes (false toRemove). This is the root cause
of W3 not showing hoe's expiry removal.
