🐛 Fixed label select ordering with infinite scroll

ref https://linear.app/ghost/issue/BER-3402/

The client-side sort used `ignorePunctuation: true` which treated `#` as
punctuation, sorting `#label` as `label`. The server's `name asc` ordering
puts `#` before alphabetical characters, so newly loaded pages appeared
in the wrong position instead of being appended to the list.
