The management cached Authentik's JWKS at startup and never refreshed it, so
when Authentik rotated its JWT signing key the management could no longer
verify tokens ('unable to find appropriate key' -> 'token invalid'), breaking
the dashboard. Set IdpSignKeyRefreshEnabled=true so management re-fetches the
JWKS on an unknown key id instead of caching forever.
NOTE: deploying this redeploys VPS-1 (the IdP host) and restarts the
management container.
