Show the last event as a relative time with a UTC tooltip (closes #567)

The "Last event" figure in the webhook page's Statistics block now shows how long ago the newest event arrived, as its two largest units of d, h, m and s with no spaces ("59s", "1m1s", "3d4h"; a zero second unit is left off). It is worked out when the page is served, and a time ahead of the server clock shows "0s". Its tooltip is the full time in UTC. With no event it still shows "none", without a tooltip. A unit test pins each unit boundary, and the headless-browser test checks the figure and its tooltip. Model: opus-5-5
