Auto-detect the Asterisk container/dir in the PSTN test checklist

Browse Source 
$CONTAINER/$EA_DIR only lived in the shell session where they were typed
by hand — a new terminal or enough time between test steps left them
empty, and an empty $CONTAINER silently collapsed
"docker exec -it $CONTAINER asterisk -rx ..." into "docker exec -it
asterisk -rx ...", failing with "No such container: asterisk" instead of
an obviously-unset-variable error. Confirmed live. Replaced the manual
pick with a docker ps auto-detect so a stale/forgotten variable can't
silently break every command in the checklist.

## 0. Before you start
Confirm which layout this box uses — commands below need the right
container name and directory:
`$CONTAINER`/`$EA_DIR` only live in the shell session where you set them —
a new terminal, a reboot, or just enough time passing between test steps
leaves them empty again, and an empty `$CONTAINER` silently turns
`docker exec -it $CONTAINER asterisk -rx ...` into `docker exec -it
asterisk -rx ...`, which fails with "No such container: asterisk" (there's
no container literally named that — it's `easy-asterisk` or
`easy-asterisk-do`). Auto-detect instead of typing it by hand, so a stale
or forgotten variable can't silently break every command below:
```bash
docker ps --format '{{.Names}}' | grep -i easy-asterisk
# easy-asterisk -> ~/docker/asterisk
# easy-asterisk-do -> ~/docker/asterisk-digital-ocean (pre-merge droplet)
CONTAINER="$(docker ps --format '{{.Names}}' | grep -m1 -E '^easy-asterisk(-do)?$')"
EA_DIR=~/docker/asterisk; [ -d ~/docker/asterisk-digital-ocean ] && EA_DIR=~/docker/asterisk-digital-ocean
echo "Container: $CONTAINER Dir: $EA_DIR"
```
Set these once and reuse them in every command below:
```bash
CONTAINER=easy-asterisk # or easy-asterisk-do
EA_DIR=~/docker/asterisk # or ~/docker/asterisk-digital-ocean
```
If `$CONTAINER` prints empty, the container isn't running at all — check
`docker compose -f $EA_DIR/docker-compose.yml ps` before anything else.
Re-run this block at the start of every new terminal session, not just
once — it's cheap and removes the whole class of failure above.
