example: add additional example demos

[Geliogabalus]

Summary

• Add multiple new JavaScript example demos: bandwidth, bus, chess, convex-hull, curves, entity-relationship-diagram, finite-state-automata, html-tasks, icons, links, logic-gates, marey-chart, paper, petri-nets, puzzle, rough, routing, sequence-diagram, uml-state-chart, and ELK layout integration
• Add bootstrap-tabs-js example demonstrating JointJS with Bootstrap tabs
• Rename container and list examples to container-ts and list-ts to clarify they are TypeScript examples
• Fix package.json dependency versions across existing examples

Test plan

• Verify new examples build successfully with yarn ensure-examples-can-build
• Spot-check a few new examples in the browser to confirm they render correctly
• Verify renamed examples (container-ts, list-ts) still build and work
