wadamesh beta_50

wadamesh beta_50 is the new stable build. It rolls up everything since beta_46 (beta_47 → beta_50). Flash it from the web flasher, or grab a -merged.bin below and flash at 0x0.

Thanks to community contributors @attakygit and @codemonkeybr.

New

• Discover app — actively sweep for nearby nodes and list everything that answers (repeaters, companions, room servers), ranked by signal, with live RSSI/SNR, a direct badge for anything in RF range, and a last-heard age. Tap a node to add it straight to your contacts.
• Wardriving — with a GPS fix, Discover logs every node it hears against your position to a CSV on the SD card and plots your RF coverage on the map as a signal-coloured track (green = strong, red = weak). A standalone on-device coverage mapper, no phone needed.
• New board: Attaky Core (ESP32-S3, 16 MB / 8 MB PSRAM), contributed by @attakygit (#158).
• T-Display P4 TFT-LCD screen model now supported alongside the AMOLED.

On-device updates

• The updater was downloading the wrong firmware on the Heltec V4-R8, ThinkNode M9, RAK Tap V2, T-LoRa Pager and Attaky (it pulled the V4 TFT build). Each board now installs its own build.
• T-Display P4: the "Get test builds (beta)" toggle and on-device updates now appear — the P4 was previously USB-only.

Fixes

• Crash that could reboot the device while typing in a chat.
• Devices stuck on the boot screen after an update with a microSD card fitted.
• Message times showing 1910 / wrong dates — they now match the clock.
• MQTT bridge settings not saving across reboots.
• Dutch keyboard typing "ij" / "IJ" on the "1" and "!" keys.
• The message box dropping the end of long messages; copy/paste cutting off long text.
• Quick messages list not scrolling; room-server names with an unusual first character showing an empty box on Join.
• Tanmatsu: only about half the emoji were reachable in the picker.

Per-board

• T-Display P4: screen timeout works (plus standby / burn-in dimming); the full-screen tools and the Snake game exit with a top-bar tap instead of trapping you; GPS (L76K) detected reliably at 9600; taller control-center dropdown; LCD backlight fixed.
• T-LoRa Pager (@codemonkeybr, #162): lock screen fixed (Backspace peek / hold-to-unlock, layout fits the wide screen); rotary encoder keeps focus in the chat list with the composer keys remapped.
• Attaky Core: on-screen keyboard works with the detachable keyboard module; POWER button toggles/wakes the screen; LoRa-clock, GPS-baud and sensor-probe fixes.
