feat(crowdsec): arm the bouncer on proxy-2

First host goes from dry-run to enforcing. proxy-2 deliberately: it is the
dual-stack member, while proxy-1 is IPv6-only and the one where every
network-shaped problem has surfaced first — the dhcpcd/resolv.conf breakage,
and a GitHub download that could not work at all. host_vars keeps the change
to one host; proxy-1 stays on the role default.

Verified before committing: ansible-inventory resolves nftables for proxy-2
and nothing for proxy-1.

Adds netbird.renner.uno to capi_whitelists first, and that is not decoration.
The bouncer's chain sits on the INPUT hook, the proxy hosts run no other
firewall, and there is therefore no conntrack rule accepting established flows
ahead of it. A ban on the management address would drop the return traffic of
the proxies' own outbound control connection and take them off the mesh, with
no inbound attack involved at all. The same reasoning already covers the proxy
addresses, which were listed from the start.

Checked at the time of writing: none of these addresses appear in the current
decision set — searched all ~15k entries. That is the state today, not a
guarantee; they are rented addresses on a hoster whose ranges do end up on
community blocklists, which is the whole reason for listing them.

The delivery path was tested end to end beforehand with a decision on
192.0.2.1 (TEST-NET-1, so no real traffic could be affected). Both bouncers
received the ban within one poll cycle — a 206-byte delta against the usual
26 — and the revocation the same way, 203 bytes, ~5s after deletion. What that
did not test is whether a packet is actually dropped, which dry-run cannot
show. This commit is what makes that testable.

+# The role defaults to dry-run for the whole netbird_proxy group, so the two
+# members can be armed one at a time. proxy-2 goes first deliberately: it is
+# the dual-stack member, while proxy-1 is IPv6-only and the one where every
+# network-shaped problem has surfaced first — the dhcpcd/resolv.conf breakage,
+# and the GitHub download that could not work at all.
+#
+# What flipping this does: the bouncer stops logging what it would block and
+# creates two nftables tables (ip crowdsec, ip6 crowdsec6) with the decisions
+# it holds. It touches no existing chain and sets no chain policy.
+#
+# Rollback is `systemctl stop crowdsec-firewall-bouncer` — a clean stop deletes
+# both tables itself. Setting this back to dry-run and re-running the play does
+# the same through the handler.
+#
+# Remove this file once proxy-1 follows and the role default moves to nftables.
