🔥 refactor: remove DefaultAgentForm UI from settings pages

Remove the user-facing Default Agent configuration form from both
the agent settings page and the service-model settings page.
The underlying store action and selectors are preserved for
programmatic use (e.g. onboarding).

Fixes LOBE-1125
