feat(rlcd): Waveshare ESP32-S3-RLCD-4.2 support on latest main

- ST7305 driver with persistent 15KB DMA buffer (fix use-after-free + WDT lockup that caused freeze after flash) - Reset timing fix: 150ms after reset, 50ms after init - DTS: i2s0 mclk 16, bclk 9, ws 45, out 8, in 10 - fixes GPIO5 conflict - i2c0 uses esp32-i2c-master, SDMMC 1-bit - device.properties: colorDepth 16, fontSize 20, DefaultDark - Amp GPIO46 init in initBoot - Buttons: two-button control GPIO18 (cycle) + GPIO0 (select) Base: origin/main f9453d89
