Every Lit dashboard called its own API with no Authorization header. On Umbraco 13
that works (cookie auth); on 17 it returns 401 against the BackOfficeAccess guard
added in #124. Because 25 of these dashboards render their empty state on any
non-ok response, the failure looked like a site with no data.

Verified on a local Umbraco 17 baseline running the rebuilt bundles: 37 dashboards
load their data, zero auth failures remain.

Also: CharLimit's manifest pointed at a stale orphan bundle that shadowed the real
one, and D4Sign, ENotAssina, Schema2Yaml and Yaml2Schema raced their token.
