The management API (used by the Astrolabe PHP app for /api/v1/apps and
/api/v1/webhooks) only accepted JWT access tokens. Opaque tokens were
sent to Nextcloud's oidc introspection endpoint, which returns
`active: false` for tokens minted for a *different* OIDC client (e.g.
Astrolabe) even when they are live — so every call 401'd. This surfaced
on the nx101294 tenant: webhook setup failed and the webhook-preset UI
(including the Files preset) showed empty, because getWebhookPresets
errors out before its `files`-always-available filter runs.
Add a userinfo-endpoint fallback in UnifiedTokenVerifier: when
introspection reports an opaque token inactive, validate it against the
discovered userinfo_endpoint (a 200 with a `sub` proves a live bearer
regardless of issuing client). userinfo returns no client_id/scope, so
such tokens are stamped `_auth_via_userinfo` and the ALLOWED_MGMT_CLIENT
allowlist is relaxed for that path only — authorization is still
enforced per-user (token sub == requested resource owner) by every
management endpoint. JWT and introspection paths are unchanged and still
enforce the allowlist.
Also bumps the astrolabe submodule to 0.29.0 (the deployed version that
exhibits the issue).
