fix(neuron): install config at /etc/neuron/, not /etc/cortex/

The neuron package was shipping its config at /etc/cortex/neuron.toml,
which implied a shared config directory between two independent
packages. Move to /etc/neuron/neuron.toml — neuron owns its own etc
dir, consistent with its own /usr/lib/sysusers.d/neuron.conf and
/usr/lib/systemd/system/neuron.service. Updated the systemd unit's
ExecStart path and the example toml header to match.
