feat(attackers): scanned vs. interacted service bucketing on detail page

Adds a new card on AttackerDetail: SCANNED · N services | INTERACTED
WITH · M services. Distinguishes port-scanners (N high, M=0) from
actual engagement (M>0) at a glance — the analyst's first question
when triaging a new attacker row.

Classifier lives in decnet/correlation/event_kinds.py, a single
source of truth for the event-type vocabulary:

- INTERACTION_EVENT_TYPES — command-family (command/exec/query/...),
  SMTP engagement (mail_from/rcpt_to/message_accepted), file/payload
  activity (file_captured/upload/download_attempt/retr), pub/sub
  (publish/subscribe), recorded TTY sessions.
- NOISE_EVENT_TYPES — DECNET-internal (startup/shutdown/parse_error/
  unknown_*).
- Everything else defaults to scan. Conservative by design: new
  template verbs show up as "scanned" until explicitly promoted.

Bucket logic: a service is "interacted" if ≥1 of its events
classifies as interaction; otherwise "scanned" if ≥1 scan event;
noise-only services drop. Disjoint by construction.

Deliberate no-schema path: compute on-the-fly in the detail endpoint
via SELECT DISTINCT service, event_type FROM logs. Small result set
(tens of pairs per attacker), cost is trivial vs. the existing
behavior/commands queries. Trade-off: one more DB round-trip per
detail view in exchange for zero ALTER TABLE migration pain and
immediate classifier-change feedback loop.

Profiler's _COMMAND_EVENT_TYPES stays as-is (strict subset of
interactions that carry executable text), with a comment pointing at
the new canonical module.
