starlette<1.0.0 Ubuntu 24.04 ( ROS 2 Jazzy)

[TAW-V]

On Ubuntu 24.04 with ROS 2 Jazzy, we had to pin starlette<1.0.0 in the venv to get the webui to work. FastAPI pulls in Starlette 1.0 which removed the old TemplateResponse(name, context) API used in webui_server.py line 182, causing a `TypeError: unhashable type: 'dict'

The fix is implemented in the latest 4.1.3 version of FlexBE WebUI that was recently pushed, but that will require updating to 4.1.3 of FlexBE Behavior engine as well.

There have been significant updates to both repos that make the upgrade worthwhile, but recognize that this would require validation of existing deployments. We do not intend to update the Jazzy binaries, but will for Kilted, Rolling, and Lyrical going forward.
