What's New

RX duty cycle (power saving) reworked — now properly tested against the datasheet, gives ~40-55% radio-off time with no packet loss on up-to-date nodes. Toggle with set rxduty on/off. (Mixed old/new meshes: keep it off on infra nodes for now. Needs preamble 32 on adjacent nodes)
Joystick UI now shows accented characters (Hungarian/Slovak/Czech/Polish/etc. names display correctly), emojis are stripped instead of showing garbage. Unlock gesture changed to Left -> OK -> Right (easier/faster than the old Back-OK-Back).
set rxduty / set radio.rxgain now also accept on / off, not just 1/0.

WisMesh Tag battery percentage was reading high — calibration corrected.
RTC clock could get permanently stuck blank after battery loss — now recovers and re-syncs.
Clock source indicator (GPS/App/Local) and display now update correctly/immediately.
Auto-shutdown no longer triggers on a brief voltage dip during transmit (needs 3 low readings in a row now).
Fixed a race in MQTT "online" status reporting on repeaters/observers.
Several small crash/overflow hardening fixes from ongoing code audit (no user-visible behavior change).
