* fix(browser): classify CSP host sources by their own origin
A Content-Security-Policy host-source without a scheme (for example
`cdn.example.com` or `*.trusted.test`) was resolved with
`new URL(token, baseUrl)`, so it became a page-relative path and was
reported as the observed page's own origin. Third-party script, style, and
connect sources were therefore misreported as approved origins, and a bare
`*` wildcard collapsed to the page origin as well.
Resolve host-sources per CSP3 \u00a72.3.1: a scheme-less source inherits the
protected resource's scheme, wildcard host/port sources stay classified as a
set of origins, and non-host tokens remain `other`. Keyword and scheme
sources are unchanged.
Adds boundary coverage for scheme-less host sources, wildcards, and scheme
inheritance against the approved-origin set.
