Shows a live banner as each step of the approach is counted, ending in
"FINAL POSITION - RELEASE!" once the 5th footfall lands. Also fixes
LiveStepDetector's peak-prominence check, which compared a candidate
footfall only to its immediate neighboring frame and silently dropped
real steps that landed across several closely-spaced frames; it now
tracks the true rise/fall trough on each side instead. Switches
PoseAnalyzer to ML Kit's faster base pose model (the accurate model was
starving the peak detector of frames on unaccelerated hardware), and
makes LiveStepDetector's stillness-based reset toggleable, currently
off for easier testing against recorded reference clips.
