fix(plugin-manager): stop crash restoring plugin fragments after process death

When a plugin dialog fragment (e.g. the AI settings dialog) is restored from saved state after process death — before the plugin has reloaded and registered its classloader — the factory's fallback was meant to substitute a placeholder Fragment. It caught ClassNotFoundException, but FragmentFactory.loadFragmentClass wraps that in a Fragment.InstantiationException, so the catch never matched and the exception propagated into a fatal crash loop.

Also catch Fragment.InstantiationException so the placeholder substitution actually runs.
