Each nft table (isolation, orchestrator-egress nat, agent->gateway route)
was re-applied as a plain `table {...}` block, which on a bare `up`
re-apply (not the systemd down->up path) would append duplicate rules or
error on the existing base chains. Use the standard delete-first pattern
(create empty, delete, recreate) so `up` lands identical state regardless
of history — the setup reproduces cleanly on a fresh install and on
re-apply, not just via a full down->up cycle.
No functional change to the resulting ruleset; only its idempotency.
