fix(web/plugins): a plugin's interface loads again, instead of an empty panel
Two separate things had to be wrong for this, and both were.

The frame's own policy locked it out. Plugin UIs moved to their own origin so a
plugin cannot act as the logged-in operator, and the plugin origin names the
console as the only page allowed to frame it. It built that name from the
incoming request — but Nitro hands the app a synthetic request with no TLS
socket, so an HTTPS console reads back as `http:`. The header said
`frame-ancestors http://host:47992` while the operator was on
`https://host:47992`, and the browser refused the frame outright
(ERR_BLOCKED_BY_RESPONSE). Nothing on screen said so; the reason was only in
devtools. The scheme now comes from the listener's own TLS state, stamped at
bind time, with x-forwarded-proto winning when something in front terminated
TLS for us — the one case where the browser's scheme is not ours.

And the port was shut. 47993 was added to the firewall definitions, but an
already-open firewall does not pick a new port up: ufw expands an app profile
into rules when you allow it and keeps those, so editing the profile on upgrade
changes nothing, and firewalld needs a reload. Every upgraded Linux host kept a
47992-only rule, silently. The packages now notice on upgrade and print the one
command that fixes it, without touching the running firewall. The NixOS module
and the container image never learned the port at all; both now open it.

Also: the console no longer mounts the frame while it is still checking whether
that origin is reachable. A firewalled port drops rather than refuses, so the
check hangs for the browser's whole connect timeout, and mounting meanwhile is
exactly the empty panel with no explanation. The card that follows now names
both causes it can be — an untrusted certificate for that port, or a closed one
— because from a browser the two are indistinguishable.

The rule is now a pure function with tests, since its failure mode is a
well-formed header that only a browser rejects.

Verified on glass against home-worker-5 (.21) and its ROM Manager plugin: the
frame was refused before, renders the plugin's UI after.
