Adds probe_forwarded to meaningful event kinds and stores it in the
bounty table as bounty_type=probe_relay with forwarded=true/false, so
the dashboard shows whether the upstream actually accepted the test email.
The Dockerfile PROMPT_COMMAND logger uses --msgid command, so the MSGID
field arrives as 'command' not '-'. The CMD rewrite block was guarded by
event_type == '-' so it never fired, leaving fields['command'] unpopulated
and cmd_text=None for every SSH session command.
Broaden the guard to also match event_type == 'command' with no existing
'command' field, which covers both the intended (MSGID=NIL) and actual
(MSGID=command) wire formats.
SSH/telnet decky containers emit shell commands via `logger -t bash "CMD …"`
which produces RFC 5424 lines with MSGID=NIL. Both parsers were leaving
event_type="-", so the behavioral profiler's `_COMMAND_EVENT_TYPES` filter
silently dropped them — the IP profile existed but no command transcripts
or artifacts. Confirmed in the wild: 44/48 events from one attacker were
event_type="-".
Rewrite event_type to "command" in both parsers when MSGID=NIL and the
msg starts with "CMD ". Correlation parser also extracts the cmd= payload
into fields["command"] so the profiler can build the transcript; collector
parser leaves fields={} to avoid duplicate pills in the dashboard.
