Replace the HRO part with the XKB part. The HRO part had shorter feet
which caused issues during soldering.

Add BD9D321EFJ to the symbol library and align it properly to the
1.27mm/0.050inch grid. Make sure to align the instances U15/U16
correctly as well as the complete Power schematic.
With that GND is now correctly connected to Pin 5 of U16.

Switch the SiLabs Radio module from MGM210PB32JIA2 to MGM210PA32JIA2.
The PA version has no secure vault but is slightly cheaper. It is
unlikely that we use the secure vault anytime soon, so let's use the PA
version.

The MOSFET 3D model did not fit the footprint, select a matching model.
Also adjust 5V routing to avoid an unnecessary via.

Deal with DRC warnings by either ignoring (like courtyard overlap of
fiducials) or fixing (removing duplicate vias).
Also use a shorter route for SWDIO.

Move the LP5569RTWR LED controller so it doesn't interfere with the
LED light diffuser if we decide to make it sit directly on the PCB.
