feat(settings): include email in default remarkModel pattern

Change the out-of-the-box remarkModel from "-io" (Inbound, Other) to
"-ieo" so newly provisioned panels include the client's email between
the inbound name and the other slot — much easier to identify which
client a generated remark belongs to. Existing installs that have
already written a remarkModel value are unaffected; only first-run /
unset defaults inherit the new pattern.
