Subject: [PATCH] Enable CO5300 AMOLED display with live watch face

Display now shows time (00:00 from reset RTC) and status line with
radio state, battery percentage, GPS satellites, and uptime counter.
Display blanking disabled until button input is implemented.
QSPI display driver confirmed working after I2C pin fix.
