- Fix LVGL scroll-momentum use-after-free reboot when a scrollable overlay
(emoji / quick-reply / add-channel / channel sheets, Wi-Fi scan, pickers,
app drawer) is freed mid-throw: new closeScrollOverlay() helper
(lv_indev_wait_release + lv_obj_del_async). Root-caused from field beta_18
coredumps.
- Radio & Mesh settings: airtime / duty-cycle readout + "Answer telemetry
requests" toggle, grouped into RADIO / MESH / SIGNAL sections.
- Accent popup dismissed on Enter-to-send (T-Deck physical keyboard).
- Heltec V4: Expansion-Kit Home env line + chart flow below the stats line
so they fit the 240x320 screen.
