Subject: [PATCH] Admin lightning talks: surface clickable slides link per
 speaker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The admin running a live lightning session needs one-click access to each
speaker's slides at the moment that speaker steps up. The slides URL was
already collected from speakers and shown on the public schedule, but the
admin page at /admin/lightning_talks did not surface it.

Adds a slides cell to each row of the admin speakers list: a red bold
"Open slides ↗" external link when slides_url is present, or a muted
"no slides yet" indicator when blank — so admins can also see at a glance
who hasn't submitted slides and chase them before stage time.

Also extends the row's grid-template-columns by one auto track so the new
cell sits inline with handle / position / time / name / title / Remove.
