* fix: host browser popups in an Orca origin-bar window instead of chrome-less child windows

A guest-opened popup previously became a default Electron child window
with no address bar, so users could not verify a popup's origin — a
phishing surface flagged in the prod-release scan of #7392. The reverted
#8332 tried gating on disposition, which is bypassable and breaks
featureless window.open() OAuth flows.

Instead, keep hosting popups in-app (preserving the shared session
partition and live window.opener handle OAuth depends on) but build the
child window ourselves via setWindowOpenHandler's createWindow callback:
a BaseWindow with an Orca-controlled origin-bar WebContentsView on top
and a content WebContentsView that adopts the pre-created popup
WebContents. The bar shows only the destination origin (never path or
query), updates on navigation, and flags plain http to remote hosts.

Also pins secure webPreferences (contextIsolation, no nodeIntegration,
sandbox, no webviewTag) on popup children via
SAFE_POPUP_WINDOW_OPTIONS, attaches guest policies to popup contents
directly (did-create-window does not fire for createWindow children),
emits the existing opened-in-orca renderer notice, and closes popups
with their opener guest.

* fix: show page title in popup title bar instead of doubling the origin

The native title bar and the origin bar both showed the origin, reading
as a doubled header. Match Chrome popup behavior: title bar shows the
page title (reset to origin on navigation so a stale title cannot
outlive its origin); the origin bar below remains the unspoofable trust
surface.

* fix: elide the start of long popup origins so the registrable domain stays visible

Adversarial review findings on the origin bar:

- The bar right-ellipsized long hostnames, hiding exactly the part that
  matters: window.open('https://accounts.google.com.<...>.evil.com',
  '', 'width=360') rendered as 'https://accounts.google.com.signin.s…'.
  Clip from the left instead (rtl container + isolated ltr bdi so host
  and port keep normal character order), matching how Chrome elides.
- Re-assert the origin on the popup's did-finish-load so a transiently
  dropped executeJavaScript write cannot leave a stale origin up.
- Re-pin view layout on enter/leave-full-screen: verified at runtime
  that HTML5 fullscreen keeps the bar visible on macOS (resize fires);
  the explicit events make that hold on every platform.
- Test hardening: fake WebContents now flips isDestroyed after
  'destroyed' so the double-close guard is actually exercised.
