Event log: show only the events with a failed or a pending delivery (closes #390)

The event log gains three links above the list: All, Failed (N) and Pending (N), carried in a `show` query parameter; any other value shows every event. Failed lists the events with a failed delivery, Pending those with one pending or retrying, each once, under the full list's 50-row limit and order. A filtered list finds the matching deliveries through `idx_deliveries_status`, looks up their events by ID and sorts them, and reads the rows of only the events shown; its counts read the deliveries alone. The line beside the heading says what a filter counts, and Replay returns to the list it was pressed in. The README and the comments naming the query parameters the service reads include `show`.
