Add the agent LLM tab -- a searchable grid of LLM provider cards with a modal for selecting specific models within a chosen provider. This is one tab in the wider agent-settings family. All tabs share the same AgentSettingsProvider wrapper.

Do NOT add custom styles, colors, or CSS overrides to ibl.ai SDK components. They ship with their own styling. Keep the components as-is. Do NOT implement dark mode unless the user explicitly asks for it.
