Summary of the Pull Request
This PR fixes an issue where the warning message in Peek was always displayed, even when not applicable.
Root cause
When non-video files were triggered, the logic did not call
IsWarningMessageVisible(string? missingCodecName)
as expected. As a result, the default UI state caused the warning message to always appear.
Fix
Updated the method signature and call sites to:
public Visibility IsWarningMessageVisible(IPreviewer? previewer, PreviewState? state)
This ensures that the logic is consistently triggered across different preview handlers and has access to the necessary context to determine whether the warning message should be shown.
