Add Configuration Maximums page for Kubermatic Virtualization

[mihiragrawal]

What

New documentation page: Configuration Maximums for Kubermatic Virtualization, under content/kubermatic-virtualization/main/configuration-maximums/. It documents the validated configuration maximums of a KubeV cluster — VMs, networks, firewall rules, subnets, routes, etc. — as discovered by the in-cluster ConfigMax benchmark tool.

Lands in main (next release); v1.1.0 is frozen.

What's in it

1. Validated maximums — customer-facing table. Embargo-clean (no VMware/vSphere naming). Uses an Accepted (objects stored) vs Sustained (objects in place while VM-to-VM latency stayed within 5 % of baseline) split so the headline numbers stay visible but honest.
2. Engineering reference — internal table with the full VMware vSphere ConfigMax comparison and measurement provenance. Marked as internal / may be trimmed before public release.
3. How we measure — discovery / target / workload-SLO run modes + the distress signals that stop a run.
4. What each number is limited by — one-line bottleneck per capability.
5. Run it yourself — prerequisites, one annotated ConfigMaxRun YAML, apply/watch/read commands, and a key-parameters reference.

For the reviewer (@Moath — decisions needed)

• Engineering table: keep it on the public page, or trim to the customer table only?
• "Validation in progress" rows (attachment templates, routable services, QoS policies, VMs-per-host): include now or omit until re-validated?
• Any numbers to soften before this is customer-visible.

Verification

Built locally with the project's Dockerized Hugo (quay.io/kubermatic/hugo:0.159.1-0), exit 0, no errors. Page renders and appears in the main section nav.
