feat(web): tools and MCP section in Agent settings, tool call IO drawer

Settings > Agent: MCP server card (endpoint, enable switch, allowed API keys,
live sessions, recent calls, copyable client config without secrets) and the
capability list (scope, risk, idempotency/replay, authorization state, 7-day
calls and failure rate, last call, schema sheet). Agent session tool cards get
a drawer with input/output schema and the redacted input/output of the call.
