Feat: Use Neptune 4 Plus built-in ADXL345 as default

Browse source 
The Neptune 4 Plus has a built-in ADXL345 accelerometer on the
mainboard. This is more reliable than the Cartographer integrated
ADXL which has version-specific pin requirements (V3: PA3, V4: PA0).

Configuration:
- cs_pin: PG11 (Neptune 4 Plus mainboard ADXL)
- spi_bus: spi2

The Cartographer ADXL config is kept as a commented alternative
for users who prefer to use it.

This fixes: 'Invalid adxl345 id (got 0 vs e5)' errors by using
the known-working mainboard accelerometer.
