fix(deploy): make the redis command flags take effect in dev and local compose

PR #4506 fixed this in deploy/docker-compose.yml, but the same broken
form is still in docker-compose.dev.yml and docker-compose.local.yml.
The redis command is one quoted script given to the inner sh -c, and
compose keeps the newlines inside the quoted string, so redis-server on
the first line runs as a complete command with no flags at all. The
--save / --appendonly / --appendfsync lines are silently never applied,
and ${REDIS_PASSWORD:+--requirepass ...} is dead too — redis takes no
password even when REDIS_PASSWORD is set.

The fix is the same trailing `\` line continuations as #4506, with the
same comment, so the three compose files read the same way.

Checked with both files on redis:8-alpine, REDIS_PASSWORD set. Before:
PING with no auth said PONG, appendonly was "no", save was the stock
"3600 1 300 100 60 10000". After: no-auth PING gets NOAUTH, appendonly
is "yes", save is "60 1". With REDIS_PASSWORD unset the server still
starts open, as before.
