LP-6 added auth.legacy-protocol-refused to the packaged schema, which this
branch also changes. The file is gzipped, so the two can't be merged line
by line: this takes main's schema and adds the Settings › Security ›
Hardening link to it again, with the hash recomputed.
Adds a link to CustomComponent/LegacyProtocols in the packaged schema's
Settings › Security, between Settings and Blocked IPs, and updates the
schema hash so admins fetch the new layout rather than a cached one.
INBUXA Admin draws the screen; this is what makes it reachable. An admin
from before that screen would show "Unknown component" here, so this
lands after the admin release that carries it.
