Test build on top of beta_29. This one is about speed: the big-mesh sluggishness is fixed, and the Spectrum analyzer is now genuinely live.

Fixed — the periodic multi-second freezes on busy meshes (#82)
Saving the contact list took up to 3 seconds at ~570 contacts and ran on the UI thread every couple of minutes — exactly the trackball/touch hesitation reported since beta_25. The save now packs the same data into a few large writes instead of thousands of tiny ones, cutting it to a fraction of the time. On top of that, the Contacts tab no longer tears itself down every 60 seconds just to refresh the "heard 2h ago" labels (they update in place now — that rebuild cost over a second on large lists and could yank the list mid-scroll), and advert bursts can no longer queue several rebuilds back to back.
Thanks to guinnessbear for the report and to Yazutsu for the first-rate timing measurements that pinned down exactly where the stalls came from.
Improved — Spectrum analyzer
- The waterfall gets a new line ~4x per second instead of once per sweep, and the trace advances across the band as it sweeps, like a bench analyzer.
- A full sweep is ~20% faster.
- The trace Y-axis now scales itself to the live signal: it expands instantly when a strong signal appears (no more clipping flat against the top) and eases back once it's gone, never zooming tighter than 30 dB.
