Add guarded Meshtext, radio2 and multi-hop OTA hardware tests

Add identity-bound app flash adapters, exact-receipt radio2 sweeps through preamble 384, measured packet-window goodput, stock-peer delivery probes, Zopfli1000 USB OTA serving and bridge outage/recovery checks. Keep dwell experiments opt-in, production timing unchanged, generated artifacts outside Git, and wire offline safety tests into CI.
