fix(web): show non-Japanese names as-is with Romaji on (e.g. ☆NoAki☆ kept its stars)

With 'show Romaji' enabled, dispArtist/dispArtistById/dispArtistParts/dispTitle
substituted the sort tag for the display name unconditionally. For non-Japanese
names the sort tag is just a sort key (leading symbols/articles stripped, so
'☆NoAki☆' → 'NoAki'), which wrongly replaced the real name. Guard the substitution
on the original being Japanese — mirroring what dispAlbumName already did — so
Romaji only applies to Japanese names and everything else shows unchanged.
