v3.2.2: Switch to SMD terminals instead of press-fit

Rationale: These are easier to manufacture (no additional step required)
and the PCB can be mounted onto a heat sink without any milling required.

Remove FUSE_DETECT circuit

Q13 was not properly tied to ground, so it was not switching on the
voltage divider. A voltage divider that is continuously on would
draw current even in deepsleep mode, so it is not viable for a BMS.

I could not come up with an easy circuit that allows monitoring the
voltage without any power consumption, so the fuse diagnosis
mechanism is removed for now.
