Issue 1: Multiple start events
Resolution:
Issue 2: Multiple gateway elements connected must be in single row
Resolution:
### Changes Implemented:
- Modified the logic to only include elements of type bpmn:StartEvent when processing starting elements.
- Added an incomingHandler to check whether an element has more than one incoming edge
- If the element has multiple incoming edges, the handler now sends the second one to the grid below.
- Updated the handling of gateways to ensure they are displayed on a single row in the grid.
