Give a summary of what the PR does, explaining any non-trivial design decisions

Support trajectory replay on web GUI.

Code is mostly complete; now need to do some clean ups, and make web GUI look prettier.

Before releasing this feature, maybe we should have added "export trajectory" feature first. It's available in headless mode, but not available on GUI yet.
