The committed version contained a literal "***REDACTED***" placeholder as
KEEPALIVED_PASSWORD, which was restored onto disk every time the real file
was deleted or the local checkout re-synced from git. This caused VRRP auth
to mismatch between keepalived-master and keepalived-backup (master picked
up the broken committed value, backup retained a stale-but-correct value),
producing a continuous "(VI_1) received an invalid passwd!" flood and VIP
instability. traefik.env is now rendered fresh from traefik.env.template by
deploy/provision-stack.py on every provisioning run and never committed.
