feat: Add a dropdown that shows the transcript in the recording summary

[GitWither]

Description

This PR implements a dropdown in the recording summary that shows the generated transcript. I'm not at a point where I can trust small local models with summary accuracy, so being able to see the transcript helps in some cases. Open to feedback on the design.
I'm not aware if this is a planned feature or something already work in progress, so feel free to just disregard this.
