Consolidate API for first release

[GiacomoCortesi]

API needs a light rework to account for:

• future development features
• transcription must relate to the video they have been generated for (right now we have the reference of the job_id which would include the information of the video file, but it is not persistent as of now because redis job queue gets periodically cleaned up)
• PATCH transcription method was generated by hand
• consolidate openapi cli command to be used to update specific things (i.e. if I just added and endpoint I want an openapi cli generator command that makes the least possible modifications to anything else)
• fix parameters naming (e.g. video_file may as well in the future be a url, make sure to use proper meaningful names)
