Two bugs causing blank display on both ESP32 Balance boards: 1. Wrong GPIO pins: RST was GPIO12 (should be GPIO14) and BL was GPIO40 (should be GPIO2) per Waveshare ESP32-S3-Touch-LCD-1.28 schematic. The previous "correction" from GPIO2→GPIO40 was itself erroneous. 2. No HUD rendering: ota_display_task only handled OTA overlay states and drew nothing in idle mode. Added draw_hud_idle() that clears the screen on first call, draws "SAULT" at scale=4 centred on the 240×240 display, and updates battery voltage (from g_vesc[0].voltage_x10) at 5 Hz.
