🟡 Changes recommended
The troubleshooting guidance incorrectly rules out host packet capture for kernel-driver deployments and recommends capinfos for per-packet metadata that requires tshark’s frame.comment field.

What changed in this PR
Adds gateway packet-capture guidance using the dataplane CLI, addressing traffic that host tools cannot see with the DPDK driver.
Changes:
- Documents capture commands, filters, metadata, file retrieval, and operational limits.
- Links NAT troubleshooting to packet capture.
- Updates health checks to show one gateway pod with two ready containers.

We shouldn't leave the user hanging on the empty capture question. Hopefully capinfos can tell them if they have an empty capture then they can know to use the other gateway, or more realistically the AI will do it

Add a troubleshooting section on capturing gateway traffic into pcapng files with the dataplane CLI, since tcpdump can't see it with the dpdk driver. Also fix the stale pod listing in the health checks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Signed-off-by: Emanuele Di Pascale <emanuele@githedgehog.com>
