perf(ci): drop dead uvicorn start from perf job (#917)

Since #915 the perf job gates only on test_frame_budget.py, which drives
the CSIProcessor pipeline in-process and makes no HTTP calls. The
"Start application" step (uvicorn + `sleep 10`) was therefore dead weight:
it existed only for the now-excluded api_throughput/inference_speed tests,
wasted ~10-15 s per main-push run, and dumped ~50 misleading
"router requires hardware setup" ERROR lines into every CI log for a
server no test touched. MOCK_POSE_DATA is server-only, unused here.

Removed the step and the vestigial env. The gated test is unchanged and
passes (verified locally, 3/3).

+- Presence detection: 100% accuracy on 60,630 overnight samples. *(Retracted — that recording was single-class (one sleeping person, 6,062/6,063 frames "present"), so a constant "yes" scores ~99.98%. Superseded by the honest 82.3% held-out temporal-triplet metric; see [#882](https://github.com/ruvnet/RuView/issues/882). Kept here as the in-place public record.)*
