Cache Composio tools and load saved settings in the UI

Tools are now cached per-org with a 5-minute TTL to avoid hitting the
Composio API on every agent run. The ComposioPanel loads the currently
saved API key status and pre-checks enabled toolkits from the snapshot,
so users see their existing configuration when opening Settings > Tools.
