Show an event's entrypoint and request headers (closes #389)

An expanded event in the event log and the event's own page now show
the entrypoint the event arrived at (its description, "Entrypoint"
when it has none, or "deleted entrypoint"; never its URL), or for a
resubmitted copy the one its original arrived at, and the request
headers, one per line, sorted by name, whitespace kept. The event log
leaves out headers that hold more than the body's 32 KiB limit, stored
or as lines, and links to the event's page, which shows them all.
Both pages draw them through one shared template, event_request.html,
and read the webhook's entrypoints once per page.
