Fixes the remaining two paths from #139: JS-level fetch()/XHR
(op_fetch_url) and dynamic ES module imports (ObscuraModuleLoader) both
built their reqwest clients with `Client::builder().build()` — no
proxy — so every JS-initiated network call silently bypassed
BrowserContext.proxy_url. (The third path, StealthHttpClient, was
already fixed in main: page.rs:61 uses with_proxy.)
Changes:
* obscura-net: expose ObscuraHttpClient::proxy_url() so callers outside
the crate can route their own reqwest requests through the same
upstream proxy. The field was already there — just lacked an accessor.
* obscura-js/module_loader: add `proxy_url: Option<String>` and
`with_proxy(base_url, proxy_url)`. ObscuraModuleLoader::new keeps the
pre-#139 direct-connection behaviour. load() builds a reqwest client
per import, threading the proxy and bubbling up "Invalid module proxy"
on bad URLs.
* obscura-js/ops.rs: replace the process-wide
`static SHARED_HTTP_CLIENT: OnceLock<reqwest::Client>` (which could
never be reconfigured after first call) with a per-request
`build_request_client(proxy_url)` that pulls the configured proxy out
of SharedState.http_client.proxy_url() each call. Per-request build
cost is ~1ms vs the network round-trip, and we no longer have a
global singleton that lies about its config.
* obscura-js/runtime: add ObscuraJsRuntime::with_base_url_and_proxy.
with_base_url delegates to it with None so existing tests / callers
are unaffected.
* obscura-browser/page.rs: thread context.proxy_url through to
with_base_url_and_proxy when constructing the JS runtime.
- obscura-net/cookies.rs: #[allow(dead_code)] on CookieEntry.same_site
(parsed today, kept for future SameSite enforcement).
- obscura-js/runtime.rs: drop vestigial BOOTSTRAP_JS const; bootstrap.js
is already embedded into the V8 snapshot via build.rs.
- obscura-js/ops.rs: prefix the four unused fields in
InterceptResolution::Continue with _.
- obscura-cdp/dispatch.rs: drop unused InterceptResolution import.
- obscura-cdp/domains/fetch.rs: drop unused Arc / Mutex / CdpEvent imports.
- obscura-cdp/domains/input.rs: prefix _button / _click_count; CDP
parses them but the JS click stub is hardcoded for now.
- obscura-cdp/server.rs: prefix _processor_handle and _ctx; drop dead
initial Ok(())/None for navigate_result/page_back - they are
unconditionally overwritten in the only loop break arm.

Allow loading local HTML/CSS/JS files via the file:// protocol,
enabling Obscura to be used for testing static sites without
running a local HTTP server.
Changes:
- Allow "file" scheme in validate_url() and validate_fetch_url()
- Add fetch_file_url() to read local files and return synthetic
HTTP responses with appropriate content-type headers
- Skip private IP / localhost checks for file:// URLs
