Show each webhook's activity in the webhook list (closes #394)

Each entry in the webhook list now shows when the webhook's last event
arrived, or "No events yet", and how many of its deliveries failed in
the last 24 hours, in red when that is not zero. The entrypoint and
target counts say how many are inactive.

The figures come from the statistics pane's own reads: the event totals
row, which now also gives the event count instead of counting every
stored event, and the pane's query over the deliveries finished in the
last 24 hours. A webhook whose event database cannot be read says so in
its entry rather than showing zeros.

+#### EventTotals and TargetTotals
+
+Running counts in each event database, read by the statistics pane at the
+top of the webhook page and by the webhook list. `EventTotals` is one row:
+
+| Field            | Type      | Description |
+| ---------------- | --------- | ----------- |
+| `events`         | integer   | Events ever stored, resubmitted copies included |
+| `events_removed` | integer   | Events retention has deleted |
+| `last_event_at`  | timestamp | When the newest event arrived (nullable; empty before the first); retention leaves it as it is |
+
+`TargetTotals` is one row per target, created by the first delivery to it:
+
+| Field                | Type    | Description |
+| -------------------- | ------- | ----------- |
+| `target_id`          | UUID    | The target (primary key) |
+| `deliveries`         | integer | Deliveries to it ever created, replays included |
+| `delivered`          | integer | Of those, how many became `delivered` |
+| `failed`             | integer | Of those, how many became `failed` |
+| `deliveries_removed` | integer | Its deliveries retention has deleted |
+| `failed_removed`     | integer | Its failed deliveries retention has deleted |
+
+Each count changes in the transaction that writes or deletes the rows it
+counts. The pane's lifetime events are `events`, and its lifetime
+deliveries and failures are `deliveries` and `failed` summed over the
+targets; each figure within retention is the same less what retention
+removed, so neither needs the rows themselves. Its last event is
+`last_event_at`, written in the transaction that stores the event, so it
+still shows once retention has removed every event. Its last-10-minutes and
+last-24-hours figures are counted from the `events` and `deliveries`
+indexes over just that window, the deliveries in one query grouped by
+target. Its failure percentage for a window is the deliveries that became
+`failed` in it out of all that became `delivered` or `failed` in it, and
+a dash when none did.
+
+The webhook list at `/hooks` shows three of the pane's figures for each
+webhook: its events within retention and its last event, both from
+`EventTotals`, and its deliveries that failed in the last 24 hours,
+counted with the pane's query. It opens each webhook's event database once
+(the handle stays open) and runs those two reads there, so its cost grows
+with the number of webhooks and, for each, with the deliveries that
+finished in the last 24 hours, never with the events stored.
