Requiring acl:Write on a local document to forward a DELETE to a remote target would be a security anti-pattern — the target endpoint enforces its own access control, and SSRF protection via URLValidator is the appropriate security layer. Extends the existing mapped-URI bypass to cover all methods and all URIs when ?uri= is present. Adds a regression test that verifies an agent with acl:Append only on /sparql (not on the root URL) can POST via proxy. Co-Authored-By: Claude Sonnet 4.6 * Move proxy logic from ProxiedGraph into ProxyRequestFilter Replace the JAX-RS sub-resource (ProxiedGraph) and Dispatcher routing with a @PreMatching ContainerRequestFilter (priority 4050) that intercepts all proxy requests — both explicit ?uri= params and lapp:Dataset matches — before AuthorizationFilter runs. ACL is no longer checked for proxy requests; access control is enforced by the target endpoint. Removes the proxy bypass hack from AuthorizationFilter and simplifies Dispatcher (no more getProxyClass()). ProxiedGraph is deleted entirely. Co-Authored-By: Claude Sonnet 4.6 * Set REQUEST_URI_HEADER on proxy client response before entity read ModelProvider / HtmlJsonLDReader requires a base URI hint (set via REQUEST_URI_HEADER on the response) to resolve relative references when parsing HTML+JSON-LD. Without it jsoup throws a NullPointerException. Mirrors the header injection done in the old ProxiedGraph.get().

The fix moves bgp-triples-map computation before the guard and conditions the append on exists($bgp-triples-map), leaving the server-rendered empty div.left-nav unstyled when there are no facets to show.
