Uniform the quoting criteria when dealing with transcripts:
- transcripts are stored as they are, no quoting in the data we store (and therefore HTML should be avoided)
- transcripts are displayed quoted, therefore disabling any effect from HTML eventually present in the content
- bring the logics to build transcript content in the api to avoid duplication
- avoid sending the transcript content to transcript-new-2, as we can generate it server side
Note: storing transcripts as a pre-formatted chunk of text is probably not the best approach, as any changes to the formatting cannot be applied to pre-existing data without a delicate upgrade. This new approach will make <br> tags inside older transcripts visible...
