/iblai-memory-tab

Add the agent Memory tab -- a toggle switch to enable/disable agent memory and a managed memories section with add, edit, bulk delete, and individual delete actions. 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.
