Subject: [PATCH] fix(kener): define REDIS_URL and drop unused databases

Kener v4 requires Redis for its BullMQ queues, caching and scheduler,
so the app crashed on startup with "REDIS_URL is not defined in
environment variables" right after printing that it was running
(issue #976). The template also spun up both a postgres and a mariadb
container while DATABASE_URL pointed at SQLite, so neither database
was ever used (issue #282).

Changes, aligned with the upstream docker-compose.yml
(rajnandan1/kener):

- Add a redis:7-alpine service with a healthcheck and persistent
  volume, wire REDIS_URL=redis://redis:6379 and make kener depend on
  redis being healthy
- Remove the unused postgres and mysql services plus their env vars
  and generated passwords; keep SQLite (upstream default) persisted
  in the kener_db volume
- Set ORIGIN to https://<domain> instead of http://localhost:3000 so
  CSRF protection works behind the generated domain
- Drop the stale /app/uploads bind mount (kener v4 only persists
  /app/database) and the obsolete compose version key

Deploy-tested on a Dokploy instance: migrations and seed complete,
schedulers start, "Kener version 4.1.2 is running!", HTTP 200 on the
generated domain, both containers stable.

Closes #976
Closes #282
