fix: pin fastapi>=0.116.0 to prevent starlette 0.46+ incompatibility (#810)

* fix: pin fastapi>=0.116.0 to prevent starlette 0.46+ incompatibility

* fix: bump fastapi>=0.116.0 in openapp_env and scaffolding templates

Address Copilot review on #810: align openapp_env package dep and the
CLI/skill scaffolding templates with the new core minimum so non-Docker
and freshly-generated envs can't land on the incompatible fastapi 0.115.x.
