Show pregame lobby chat in admin session logs

Admins can now see the full lobby chat transcript (who said what,
when) at the top of a session's log view, alongside the existing
per-player terminal logs. Also swaps the log tabs' inline onclick
handler for a data attribute, in prep for moving the tab-switching
script out of the template.
