Adira c2fe0a6475 fix(http): honor X-Forwarded-Prefix when proxy strips the prefix (#9614)
* fix(http): honor X-Forwarded-Prefix when proxy strips the prefix

Closes #9145.

Two related issues kept the React UI from loading when a reverse proxy
rewrites a sub-path with prefix-stripping (e.g. Caddy `handle_path`):

1. `BaseURL` only computed a prefix from the path StripPathPrefix had
   removed, so when the proxy strips the prefix before forwarding, the
   request arrives without it and the base URL was returned without a
   prefix. Extract a `BasePathPrefix` helper and add an
   `X-Forwarded-Prefix` header fallback so the prefix is recovered.
2. `<base href>` only changes how relative URLs resolve; the build
   emits path-absolute references like `/assets/...` and
   `/favicon.svg`, which still resolve against the origin and bypass
   the proxy prefix. Rewrite those references in the served
   `index.html` so the browser requests them through the proxy.

Adds unit coverage for `BaseURL` with a pre-stripped path and an
end-to-end test for the proxy-stripped scenario.

* fix(http): gate X-Forwarded-Prefix through SafeForwardedPrefix in BasePathPrefix

BasePathPrefix consumed X-Forwarded-Prefix directly, so a value the
codebase elsewhere rejects (e.g. "//evil.com") slipped through and was
interpolated into the SPA index.html — both into the path-absolute asset
URL rewrite in serveIndex (turning "/assets/..." into "//evil.com/assets/...",
a protocol-relative URL that loads JS from a foreign origin) and into
<base href>. Route the header through the existing SafeForwardedPrefix
validator that StripPathPrefix and prefixRedirect already use, and
HTML-escape the prefix before injecting it into the asset rewrite as
defense in depth against attribute breakout.

Tests cover //evil.com, backslashes, control chars, CR/LF and a missing
leading slash; the integration test asserts an unsafe prefix can't poison
asset URLs.
