Summary

Adds support for the Waveshare ESP32-S3 Touch AMOLED 1.8".

• New device: Devices/waveshare-s3-touch-amoled-18 (devicetree, module wiring, expander reset, LVGL scaling/insets)
• New NXP PCF85063A RTC driver (Drivers/pcf85063-module)
• Sleep/wake via AXP2101, TCA9554 expander, ES8311 audio, QMI8658 IMU, FT5x06 touch, SH8601 panel
• UI insets set to 22 px on all edges

Reliability fixes

• SH8601: use internal DMA bounce buffers instead of PSRAM-direct QSPI DMA, avoiding DMA TX underflow and panel desync under PSRAM contention
• FT5x06: correct register constants and raise the I2C transaction timeout

Board tuning

• I2C0 at 100 kHz
• SPI2 max-transfer-size 8192 (8 KB) instead of 64 KB

Test build

python3 device.py waveshare-s3-touch-amoled-18 + idf.py build on main @ 7462d32d (#714) → BUILD_EXIT=0 (build/Tactility.bin, 4,006,688 bytes, 36% partition free).

Supersedes #708, which was auto-closed when the develop base branch was deleted.
