fix(c6): drive AMOLED-2.16 C6 panel as CO5300, side-USB orientation

platformio.ini and the board files labelled the Waveshare
ESP32-C6-Touch-AMOLED-2.16 as an SH8601 panel, when it actually uses a
CO5300 (per the official spec) -- the same controller as the S3
AMOLED-2.16. It still rendered because display.cpp grafted CO5300-style
manufacturer registers (a 0xFE page-switch writing the 0x19/0x1C
driving-voltage registers) onto the Arduino_SH8601 class, and both
controllers speak standard MIPI DCS for pixel writes.

Rebase onto Arduino_CO5300 (matching the S3 AMOLED-2.16 sibling) and keep
only the page-0x20 panel-driving registers (0x19/0x1C) the class init
omits; everything else (0xC4/0x36/0x53/0x51/0x63/0x29) is now covered by
Arduino_CO5300::begin().

Adopt the CO5300 rotation-0 default (MADCTL 0x00) instead of the old forced
0x30 transpose, orienting the board with the USB port on the side (the
preferred desk orientation). Touch axis mapping is re-derived and tap-tested
on hardware to match: swap=false, mirror=(false,false).
