R5 is 27k in the BOMs and 72k in the layouts

[ramereth]

R5 sets the MP1584 enable divider, and the files disagree:

Source	Value
control_bom.csv, control1_bom.csv	27k
control_xy.csv, control1_xy.csv	27k
Rendered schematic (control.png)	27k
control.pcb, control1.pcb, control2.pcb	72k

With R4 = 100k and the MP1584's ~1.5 V EN threshold:

• 27k -> turn-on at 1.5 * (100+27)/27 = ~7.0 V
• 72k -> turn-on at 1.5 * (100+72)/72 = ~3.6 V

The README advertises a 5-30 V input. At 27k the board would not start at 5 V at
all, so which value is actually fitted determines whether the product does what
it says.

This needs measuring on a physical board — it can't be resolved from the
files, since four of them say one thing and three say the other.

Detected by tools/check_bom.py, and baselined in
tools/known_bom_issues.txt so CI blocks on new drift meanwhile. Delete that
entry when this is resolved.

Related: C4 is 0.01uF on the schematic (a 10 nF bootstrap cap is conventional
for the MP1584) but ordered as 100nF in both BOMs.
