jgrusewski 8bb7ffd897 diag(fxt-data-audit): predecoded MBP-10 sidecar audit binary ...

One-shot diagnostic that loads a .dbn.zst via
load_or_predecode_mbp10 and reports symbol distribution, per-symbol
price stats (min/p1/p50/p99/max for bid_px[0]/ask_px[0]), outlier
counts (zero-price, huge-price >$100k, zero-price-with-size),
and first-record samples per symbol.

Built to investigate the 18% sentinel-laden trade residue in the
ISV stop-controller cluster smokes (97 zero, 85 i32::MAX, 14 weird-
other). The controller path is structurally correct; remaining bad
records hypothesized to originate from source MBP-10 data (mixed
symbols, corrupt records, or unreported instrument families).
