drop_pii seems broken

[cpiemontese]

Traces on the PII-less bucket now have PII in them:

example: s3://prima-uk-pricing-engine-production/traces/version=v3/year=2023/month=06/day=25/lineage_id=6bbe07ac-0fae-4a23-8029-8d13fb2089ed/public-19ae69ec-0d5c-4a1c-9374-d7ecefb061f3.gz

It seems the code doesn't try to drop PII from lists of structs. e.g. additional_drivers is missed out here:

def drop_pii(%MODULE{} = value) do
value = Map.from_struct(value)
value = Map.update!(value, :proposer, &MODULE.drop_pii_proposer/1)
value = Map.update!(value, :vehicle, &MODULE.drop_pii_vehicle/1)
value = Map.update!(value, :cover, &MODULE.drop_pii_cover/1)
value = Map.update!(value, :meta, &MODULE.drop_pii_meta/1)
Kernel.struct(MODULE, value)
end

But in the example above, the proposer's PII is also present...
