fix(annotation): show new version warning even without annotation

Change has_new_version logic to compare current file version with
latest version, regardless of whether annotation exists.

Before: Only show warning if annotation exists and version is outdated
After: Show warning if current file is not the latest version

This ensures users are informed when viewing an old file version,
even if they haven't started annotating yet.
