refactor(dev): replace v5:sync-dev-lima-servers with V5DevLimaSeeder

Switch Lima VM dev-environment sync from a custom Artisan command to a
database seeder. The seeder creates/updates the Development-Lima cluster
and its two servers idempotently, reading ssh_user from the
COOLIFY_CLI_SSH_USER env var (exposed via config('coold.dev_ssh_user')).

dev.sh now passes COOLIFY_CLI_SSH_USER and runs db:seed instead of
building per-server --server flag arrays.
