MailDrawer was reading fields.date / from_addr / message_id —
all wrong; actual log field names are date_hdr, from_hdr,
message_id_hdr, to_hdr. The mail table in AttackerDetail
showed only DECNET capture time and used from_addr instead
of from_hdr. Add a DATE (attacker) column so the attacker-
supplied Date header (including timezone) is visible at a
glance — useful for correlating campaigns like the Tiscali
run where IPs used distinct TZs (+0800 vs -0700).
