route-health: per-gateway failover, iperf3 checks, GRE detection fix

- Flush routes per dead gateway instead of waiting for entire group to die - Add iperf3 bandwidth (success=0 → dead) as third health signal - Ping threshold: >=50% loss is now dead (was 100%) - State tracking per gateway (.state/GROUP/gw-TAG/) - GRE detection: use link UP instead of RX bytes delta (fixes false disconnected status on idle tunnels) - Timer interval: 20s (was 1min) Co-Authored-By: 's avatarClaude Opus 4.6 <noreply@anthropic.com>
