Index the event-tier columns the sweeps, event log and retention scan (closes #314)

The per-webhook tables declared no secondary indexes, so the recovery
and sweep queries (by delivery status, every minute), the event log
(deliveries by event, results by delivery) and retention (events by
age) each scanned a whole table. Add indexes through GORM model tags so
AutoMigrate creates them on a fresh and on an existing per-webhook
database. events.created_at is indexed by overriding the embedded
BaseModel field on Event alone, leaving the other tables' created_at
unindexed. A test drops the indexes from an opened database, reopens it,
and asserts the open recreated them. The README Data Model section lists
the indexes.

-### Running under upaas
-
-[upaas](https://git.eeqj.de/sneak/upaas) builds the image from this
-repository's `Dockerfile` and runs it. The app needs:
-
-- **Network and port:** add no port mapping in upaas. upaas publishes
-  every mapped port on all interfaces of the host
-  ([upaas issue 113](https://git.eeqj.de/sneak/upaas/issues/113)),
-  which would put the plain-HTTP admin UI and receiver there. Instead,
-  set the app's Docker Network in upaas to your reverse proxy's Docker
-  network; the proxy then reaches the app at `upaas-` followed by the
-  app name, port `8080`. Leave `PORT` unset: the image's health check
-  probes `8080`.
-- **Volume:** one host directory mounted at `/var/lib/webhooker`.
-  upaas bind-mounts the host path it is given and does not create it,
-  and the container does not start unless UID 1000 owns it (see
-  [Running with Docker](#running-with-docker)). Create it before the
-  first deploy:
-
-    ```bash
-    mkdir -p /path/to/data
-    chown 1000:1000 /path/to/data
-    chmod 750 /path/to/data
-    ```
-
-- **Environment variables:**
-    - `WEBHOOKER_ENVIRONMENT=prod`
-    - `TRUSTED_PROXIES`: your reverse proxy's address on that Docker
-      network. The `remoteIP` field of the `http request` log line for a
-      request that came through the proxy shows it; the health check's
-      own lines show `::1`. See [Trusted proxies](#trusted-proxies).
-    - Leave `BIND_ADDRESS` and `DATA_DIR` unset: the image sets
-      `BIND_ADDRESS` to `0.0.0.0`, and `DATA_DIR` defaults to
-      `/var/lib/webhooker`.
-    - Everything else is optional; see [Configuration](#configuration).
-- **Health check:** the image's own, which requests
-  `/.well-known/healthcheck`. upaas reads the container's health 60
-  seconds after a deploy and marks the deploy failed unless it is
-  `healthy`.
-- **First run:** the first start prints the `admin` password once, in
-  the banner described under [The admin account](#the-admin-account),
-  to the container's log. upaas names the container `upaas-` followed
-  by the app name, so for an app named `webhooker`:
-
-    ```bash
-    docker logs upaas-webhooker
-    ```
-
-  If the password is lost, stop the container, set a new password with
-  the app's own image and volume, and start it again (see
-  [Recovering a lost admin password](#recovering-a-lost-admin-password)):
-
-    ```bash
-    docker stop upaas-webhooker
-    docker run --rm --volumes-from upaas-webhooker \
-        "$(docker inspect -f '{{.Image}}' upaas-webhooker)" \
-        /app/webhooker resetpw -generate admin
-    docker start upaas-webhooker
-    ```
