fix: update compose submodule to pick up backup network fix

The backup_stack.service was failing because the deployed compose.yml
still had backup_net declared as external: true, but the network was
never created externally.

PR #45 on the compose repo (d7449e9) already fixed this by changing
to driver: bridge, but the infra submodule was still pinned to a
pre-fix commit.

This updates assets/compose to d7449e9 so the next nixos-rebuild
switch deploys the fix.
