* fix(auth): validate wildcard permission patterns and warn on deny-list stripping
Permission.IsValidPattern rejects inert wildcard spellings (such as
"workflows*:delete") that parse but can never match. The grant boundary,
stored-permission, and external-authentication options validators reject them
at authoring time, and PermissionGrantValidator applies the same check to
incoming grants.
ExternalAuthenticationOptionsValidator now warns (never fails) when
DeniedPermissions is non-empty, because any non-empty deny list refuses every
wildcard grant that could reach a denied permission -- including the seeded
administrator role's "*". The validator takes an ILogger, and
AddExternalAuthenticationServices registers logging alongside its other
framework dependencies (TryAdd-based, so host logging configuration wins).
The operational consequence is recorded in the authorization-model migration
guide.

* fix(auth): report subtree grants whose verb nothing under them supports
'workflows/*:frobnicate' reached a non-empty subtree and was therefore
treated as resolved, so the startup audit stayed silent about a grant
that cannot authorize anything. Require at least one reached descriptor
to support a concrete verb; verb wildcards keep the reach-only check.
