central-migrate invocations were run via bare `cen "$VENV/bin/central-migrate"`,
which does not set the working directory or source the EnvironmentFile that the
systemd unit provides. This caused the pre-flight --check to fail during the
v0.14.6 deploy with `PermissionError: [Errno 13] Permission error: '.env'`
because central-migrate tried to read .env from the caller's cwd instead of
/opt/central, and the DB DSN was missing.
The daemons themselves are unaffected — they always get WorkingDirectory=
/opt/central and EnvironmentFile=/etc/central/central.env from systemd. The
deploy script is the only place that invoked central-migrate outside that context.
Fix: add ENV_FILE=/etc/central/central.env to the config block and a
cen_migrate() helper that wraps every central-migrate call with:
sudo -u central bash -c "cd /opt/central && set -a && . /etc/central/central.env && set +a && /opt/central/.venv/bin/central-migrate <args>"
Replace all four bare invocations (--check preflight, --dry-run, apply,
--check post-deploy) with cen_migrate. Exit-code propagation is unchanged —
bash -c forwards the inner exit status, so set -e / the ERR trap still fires
on non-zero exits.

Codifies the previously-manual tag-based deploy of central on CT 104.
Performs pre-flight drift check, mandatory pg_dump, detached-HEAD
checkout + uv sync, interactive confirm, migration apply, service
restart, and health-check verify. ERR trap prints rollback instructions.
