Claude 2d7b9f8d56 traccar: scripted, idempotent ntfy push-notification setup
Traccar has no native ntfy integration, but its "SMS" notification
channel is a generic HTTP webhook (sms.http.* config) under the hood —
pointing it at ntfy's JSON publish API instead of a real SMS gateway is
a well-known trick. Adds an opt-in prompt during install (or reruns)
for an ntfy server URL — self-hosted on this box, a different server
entirely, or public ntfy.sh — a topic name, and optional username/
password if that topic needs auth.

Everything lands in .env only: NOTIFICATOR_TYPES, SMS_HTTP_URL,
SMS_HTTP_TEMPLATE, and (if given) SMS_HTTP_USER/SMS_HTTP_PASSWORD.
traccar's env_file: .env already passes these straight through to the
container with no docker-compose.yml changes needed, since Traccar's
env-var config naming convention already matches these key names
exactly. The topic name itself isn't consumed by Traccar (it's set
per-user via the web UI's Phone field), so it's stored as a `#
NTFY_TOPIC=` comment line purely so reruns can recall it and so it's
discoverable on disk.

Reruns default every prompt to whatever was configured last time
(reading it back out of the existing .env), so accepting the defaults
is a no-op — the same non-destructive-by-default pattern already used
for the DB password.

Fixed a heredoc bug caught while testing this: `${_NTFY_ENV_BLOCK}
TRACCAR_ENV` on one line never matches the heredoc terminator, because
bash matches heredoc delimiters against the literal source line before
variable expansion, not after — regardless of what the variable
expands to. Moved the terminator to its own line, matching the
${_CADDY_NET_SECTION} / TRACCAR_COMPOSE pattern already used a few
lines above for the same reason.

Verified: bash -n, and four full install runs (ntfy disabled, enabled
without auth, enabled with auth, and a rerun accepting defaults) with
`docker compose config` confirming SMS_HTTP_TEMPLATE's JSON and all
other values resolve correctly through env_file with no compose-level
escaping needed.

# Traccar
GPS tracking server. Track phones, vehicles, and assets via the Traccar
Android/iOS app, OwnTracks, or any of 200+ supported device protocols.
- Web UI: http://localhost:8082
- No default login — Traccar ships with no built-in account. Open the web UI
and register the first user; it's automatically made admin. Self-registration
stays open to anyone who reaches this server until you turn it off, so do
this right away, then go to Settings → Server → Permissions and uncheck
Registration.
- Device protocols: ports 5000-5150 (TCP + UDP; 5038/tcp, 5060/tcp+udp, and
5061/tcp are skipped — reserved for Asterisk's AMI and SIP if this box also
runs Asterisk from this repo, which gets priority on those ports)
- App data: \`data/\` and \`logs/\`
- Database: PostgreSQL (\`traccar-db\` container, data in \`db/\`)
- All database settings (name, user, password) live in \`.env\` — Traccar
reads them directly via env vars, nothing is duplicated in a config file.
Change the password there (then recreate both containers) if you need to
rotate it.
- Autoheal: \`traccar-autoheal\` restarts the \`traccar\` container if its healthcheck fails
