+/**
+ * Modal for connecting / managing a Composio toolkit.
+ *
+ * Mirrors the flow, positioning, and portal/backdrop plumbing of
+ * `SkillSetupModal` so the two feel identical to the user:
+ *
+ *   disconnected → "Connect" button → POST composio_authorize →
+ *   open connectUrl via tauri-opener → poll listConnections until
+ *   the toolkit flips to ACTIVE → "Connected" success screen with
+ *   a "Disconnect" action.
+ *
+ * Redundant refetches from the polling hook in `useComposioIntegrations`
+ * keep the Skills page badge in sync too, so the card reflects the new
+ * state as soon as the modal closes.
