Merge meshcore-dev dev with routing, WiFi and power-policy compatibility

Integrate upstream 1.18.0, delayed direct ACK forwarding, zero-scope routing, Waveshare LR1121 and dynamic WiFi variants. Preserve fork chemistry-aware power management and bounded multi-interface UI; retain retry/dedup safety while adding upstream ACK delay. Qualify LR1121 band power and HP-only Morse handling with native regressions.
