ci(robocasa): smoke-eval 10 atomic tasks instead of 1

Broader coverage in the benchmark CI job: evaluate SmolVLA on ten
fixture-centric atomic RoboCasa tasks (one episode each) instead of
just CloseFridge. The tasks are all drawn from TARGET_TASKS.atomic_seen
and selected to avoid object-manipulation categories that would require
the objaverse/aigen asset packs (we only ship objs_lw in the Docker
image, paired with obj_registries=["lightwheel"] on the runtime side).

Tasks: CloseFridge, OpenCabinet, OpenDrawer, TurnOnMicrowave,
TurnOffStove, CloseToasterOvenDoor, SlideDishwasherRack,
TurnOnSinkFaucet, NavigateKitchen, TurnOnElectricKettle.

`scripts/ci/parse_eval_metrics.py` already handles multi-task output
via the `overall` key, so no parser changes needed. Bumped the metrics
artifact's task label to `atomic_smoke_10` to reflect the grouping.
