Add a "Re-transcribe" button to easily resubmit a file if the first pass has too many errors

* The Problem: Sometimes AI transcriptions glitch, hallucinate, or just struggle with the audio on the first try. Right now, if a transcript is unusable, users have to delete the entry, manually re-upload the heavy audio file, and start completely from scratch. This wastes both the user's time and their internet bandwidth. * The Fix: Add a simple "Resubmit" or "Run Again" button on the file's page. Since the audio is already hosted on WaveAI's servers, the system can just ping the AI engine to try again (perhaps allowing the user to tweak a setting, like the language or speaker count, before re-running). * Bonus Benefit: This saves WaveAI server bandwidth (by eliminating redundant file uploads) and drastically reduces user frustration by turning a tedious do-over into a single click.
