"Retry Summarization" triggers an entirely new transcription prior to an attempted re-summarization

[mattnudi]

Expected Behavior:
When user hits "retry summarization", the app will feed the existing transcription from the sqlite database into the summarizer model and output an updated summary in the UI.

Actual Behavior:
App develops an entirely new transcription using the Whisper model selected and then well proceed to retry the summarization. This can take quite a long time for long audio transcriptions.
