Resolve imported connectors by MCP server name (#35856)

## Why

Imported session attribution can identify an MCP server by its configured name
instead of the UUID stored in the session manifest.

## What changed

Match attributed MCP servers against normalized manifest names without regard to
case, while retaining UUID matching.

## Testing

Add focused coverage for both name- and UUID-based attribution.
