Merge pull request 'fix(status): read the public Kuma page, with notices scoped by a prefix' (#486) from fix/status-banner-public-page into lotus

The banner read Kuma's "matrix" status page, which was merged into "public"
on 2026-10-11, so it has returned 404 since and the banner stayed silent
(by design it fails quiet). Point it at "public", whose Matrix group is now
split into Homeserver / Voice calls / Discord.

That page is shared with other services, so add an optional noticePrefix:
only incidents and maintenance titled "Matrix: ..." reach Lotus users, shown
without the prefix. A media server's maintenance can't say messages may be
interrupted, and the Discord group can't raise a banner at all.
