Break long values on the webhook page and event log at phone width (closes #391)

At phone width, the event log cut off long event IDs and content types along with the statuses and times after them, and the webhook page ran long names past their cards and scrolled sideways. Elements that hold only a long value (a webhook, target or entrypoint name or description, an event ID, a content type) now break inside it, and the event log's title row wraps; rows themselves still wrap rather than squeeze. Wide screens are unchanged. A 390-pixel browser check of both pages, an event's attempts open, fails when anything runs past the page's or a card's edge or the page scrolls sideways.
