The mgmt REST API has bound 0.0.0.0:47990 by default since ae51276 so paired
clients can browse the game library over mTLS, but every packaged firewall
opener still excluded 47990 and the docs still claimed it was loopback-only.
On any host with an active firewall (ufw/firewalld) the LAN game-library
feature was silently broken.
Add 47990/tcp to the native firewall profiles (punktfunk.ufw [punktfunk-native]
+ punktfunk-native.xml) and correct the stale "loopback-only by default" text
across the debian/arch/bazzite READMEs and the docs site (incl. the factually
wrong --mgmt-bind default in host-cli.md, 127.0.0.1 -> 0.0.0.0). Opening the
port adds no admin exposure: off-loopback mgmt::require_auth serves only the
read-only status/library allowlist to a paired client cert; the bearer-token
admin surface stays loopback-only regardless of the bind.
Windows was already sound (shared parse_serve binds 0.0.0.0; service.rs already
firewall-opens 47990) — add a clarifying comment so the rule isn't mistaken for
accidental over-exposure.

CachyOS ships ufw enabled by default (firewalld is not installed) — verified live
on the .21 box — but the docs and shipped firewall openers claimed "CachyOS enables
firewalld by default". Correct that everywhere and ship a ufw application profile
(the one-liner analogue of the firewalld service files):
- packaging/linux/punktfunk.ufw (new): [punktfunk-native], [punktfunk-gamestream],
[punktfunk-web] profiles, installed to /etc/ufw/applications.d/punktfunk by the
Arch (CachyOS) and .deb host packages. `sudo ufw allow punktfunk-native`.
- packaging/linux/punktfunk-web.xml (new): firewalld service for the optional web
console (TCP 47992), installed by the host package on arch/deb/rpm. Neither the
native nor gamestream opener covered 47992, so a firewalld/ufw host that enabled
punktfunk-web could not reach the console over the LAN.
- Fix the "CachyOS enables firewalld" claim in arch.md, arch/README.md,
debian/README.md, both firewalld service .xml comments, and the pacman scriptlet;
firewalld now attributed to the spins that use it (EndeavourOS, Fedora/RHEL).
- Docs present both one-liners (ufw + firewalld) whichever firewall you run, plus a
console-opener step; postinst/scriptlet hints detect ufw as well as firewalld.
The native data plane stays hole-punched (ephemeral UDP, no fixed port) — its
openers correctly open only 9777/udp + mDNS; the stale "open a UDP range" note is
replaced with the accurate outbound-UDP explanation.
