[Rework] Do not lowercase all data send to ClickHouse
A lot of strings stored in ClickHouse are case sensitive according to standards - store them in original case. We can always can use 'lower(field)' in a ClickHouse query, but if string was lowercased by Rspamd nothing can be done to recover lost information. Lowercase domain parts of addresses - domains are not case sensitive and storing them in lower case will simplify queries.
