springmin 8861d4b7f2 ohos: add the OpenHarmony platform host ...

Tier-3 community port (maintainer: springmin), rebased onto the merged
document-provider abstraction (#84) and the opener seam (#80).

- platform/ohos: Slint backend (XComponent window adapter, software renderer
  with the experimental femtovg/wgpu path, input/IME, clipboard, system
  fonts), the NAPI cdylib that builds a PlatformContext (app-private paths,
  DocumentProvider over the ArkTS pickers, Asset Store credential store,
  loopback OAuth broker, external URL opener, notification publisher) and
  calls flectar_mail::run, the demo crate, the ArkTS shell and the build and
  packaging scripts (bundle name configurable, defaults to
  com.flectar.mail_ohos).
- src/platform/ohos.rs: PDFium directory, renderer name, thread priority,
  preview lifecycle, email font directory; OpenHarmony stays under the
  mobile capability alias.
- patches/fontique + crates/fontique: the Fontconfig opt-out as a patch queue
  applied by the platform/ohos workspace, verified from quality.yml.
- .github/workflows/ohos.yml: manually dispatched tier-3 workflow, unsigned by
  default, signing material only from the FLECTAR_OHOS_* secrets.
- src/documents.rs: run_request blocks the calling thread on mobile hosts;
  the picker covers the window, and keeping the presentation thread idle is
  what OpenHarmony needs (verified on device; desktop keeps the runtime
  request for the native dialog).
- The email renderer and the compose editor load platform::email_font_dir()
  and the Han fallback, so CJK mail bodies and composed text render with the
  platform fonts.
- New-mail notifications: a publisher seam fed by CoreEvent::MailNew; the host
  publishes through @kit.NotificationKit.
