fix(android): hold BOTH Wi-Fi locks while streaming — HIGH_PERF alone is a no-op
The baseline stream held only WIFI_MODE_FULL_HIGH_PERF, which is deprecated
AND non-functional on recent Android — so with the low-latency toggle off (the
default) Wi-Fi power save stayed fully active: downlink delivery clumped at
beacon intervals (a few hundred ms of latency mush, sawtoothing bitrate) and
the AP's power-save buffer periodically overflowed, killing whole frames every
few seconds (the host log's alternating loss_ppm=0/50000). Now every stream
holds FULL_LOW_LATENCY (API 29+, the only effective power-save disable;
foreground + screen-on, which a stream always is) AND FULL_HIGH_PERF (covers
older releases) — the same pair Moonlight holds. The experimental toggle no
longer selects the lock mode.

Also: declare tracing's "log" feature explicitly in the native crate (core
transport warnings → logcat must not hinge on quinn's default features), and
align the low-latency toggle's copy with its actual scope.

# as `log` records when no tracing subscriber is set (always, here). Today that feature happens to
