RenameRecordingDialog was 230px tall for ~225px of stacked content —
the file-name textbox clipped (old client area ~193px). Height is now 276
(+20%). Integration test shows the real dialog in the app host and asserts
the textbox bottom edge stays inside the client area; the dialog's Icon moved
to the explicit /ytLive;component/ URLC form MainWindow already uses so tests
can construct it (root-relative /Assets/... only resolves in production via
Application.ResourceAssembly).
Dependency fix: MainViewModel.Shutdown() now calls
_fullScreenDetector.StopWatching(). The global EVENT_SYSTEM_FOREGROUND hook
was never unhooked; after VM collection the next foreground event invoked a
garbage-collected WinEventProc delegate, crashing the whole test run. Harmless
in production (exits the process) but fatal in the multi-window test host.
Reference: WPF WinEvent hook lifecycle guidance — SetWinEventHook callbacks
must be unhooked before the owning object is collected (obs-projector
fullscreen-detection pattern).
