feat(analytics): add analytics tracking to MCP server components

- Track MCP server additions with configuration method (manual/preset/import)
- Monitor server connections and disconnections with success metrics
- Record server removal events with connection state
- Track MCP tool invocations with source attribution
- Monitor connection errors with retry attempts
- Add performance tracking for server operations

These metrics help understand MCP server usage patterns and
identify connection reliability issues.
