v1.2.9: fix UI build for youtube_via_relay (v1.2.8 CI abandoned)

v1.2.8 tagged cleanly but CI failed compiling mhrv-rs-ui with:

  error[E0063]: missing field `youtube_via_relay` in initializer of
  `mhrv_rs::config::Config`

When I added the youtube_via_relay field to the main Config struct
in 09f1f5f, I missed the struct-literal construction in src/bin/ui.rs
(FormState::save_to_config) and the ConfigWire serializer.

Fixed here:

- Added youtube_via_relay field to FormState (line 214), read path
  (line 291), default path (line 316), and the save path (line 451)
- Added youtube_via_relay field to ConfigWire (line 493) with
  skip_serializing_if on false, plus its From impl (line 544)

UI still doesn't expose a checkbox for the toggle — it's config-only
for now, same treatment as normalize_x_graphql. A future PR can add
the checkbox to the Advanced pane.

v1.2.8 tag exists but has no GitHub Release (release job skipped
on failure); v1.2.9 is the clean cut. Same payload as v1.2.8 plus
this fix.

 • گزینهٔ ‫`youtube_via_relay`‬ (issue #102): پورت شده از ‫Python‬ بالادست. وقتی فعال شود، ترافیک یوتیوب از مسیر ‫SNI-rewrite‬ خارج می‌شود و از طریق ‫Apps Script‬ می‌رود تا فیلتر ‫SafeSearch-on-SNI‬ گوگل دور زده شود. ترید-آف: ‫User-Agent‬ ثابت می‌شود روی ‫Google-Apps-Script‬ و سهمیهٔ روزانهٔ شما مصرف می‌شود. پیش‌فرض خاموش

 • اعتبارسنجی ‫TLS‬ در ‫scan-sni‬ (PR #98): درخواست ‫DoH‬ به ‫dns.google‬ از ‫NoVerify‬ به ‫webpki roots‬ سوئیچ شد تا یک ‫on-path MITM‬ نتواند ‫PTR‬های جعلی برگرداند و pool ‫SNI‬ را مسموم کند

 • Real-IP leak fix (issue #104): extended the forwarded-headers filter in the Apps Script relay path to strip every identity-revealing header (`X-Forwarded-For`, `X-Real-IP`, `Forwarded`, `Via`, `CF-Connecting-IP`, `True-Client-IP`, `Fastly-Client-IP` and 10 more) before we ship the request to Apps Script. If a user sits behind a local proxy (xray/v2rayNG) or a browser extension that inserts any of these, the real IP no longer leaks through the relay path to the origin
 • `youtube_via_relay` config toggle (issue #102): ported from upstream Python. When enabled, YouTube traffic opts out of the SNI-rewrite tunnel and goes through Apps Script instead, bypassing Google's SafeSearch-on-SNI filter that sometimes marks normal videos as "restricted." Trade-off: adds the fixed `Google-Apps-Script` User-Agent and counts YouTube against your daily quota. Off by default
 • scan-sni chunked-DoH fix (PR #97): `dns.google` replies with `Transfer-Encoding: chunked`; the raw payload was going to serde_json with chunk framing still embedded, so every PTR parse failed and scan-sni discovered nothing. Proper HTTP-body parsing now (chunked + Content-Length), plus unit tests
 • scan-sni TLS verification (PR #98): the DoH client to `dns.google` was using `NoVerify` — an on-path MITM could forge PTR answers and poison the discovered SNI pool. Switched to the normal webpki root store; the rest of the scan flow is unchanged
+• UI build fix for `youtube_via_relay`: the new config field was added to `Config` but not propagated to `FormState` / `ConfigWire` in `src/bin/ui.rs`, so v1.2.8's CI failed compiling `mhrv-rs-ui` with `missing field youtube_via_relay in initializer of Config`. v1.2.8 tag exists but no Release assets — v1.2.9 is the clean cut.
