Allow us to change the default green "Transcribed" label

All our transcripts still require manual review. Unfortunately, Sonix.AI’s default label is a little unintuitive because it just says “Transcribed” with a green label.

We’d like to have the option to change that, e.g,. we make it so the default label is orange with “draft” or “needs review”.

Currently, Sonix.AI only allows new labels but does not allow to change the default “Transcribed” label.

Because we already have so many files, changing the default label should change it for all files that have the default label (aka rename an in-use label).
