feat: Audio narration (#673)

* feat: Add audio narration feature while recording

* feat: Remove implicit scrubbing in display_event function and recursively convert reqd properties to str

* feat: Add transcribed text to dashboard visualisation

* feat: Use recording id as foreign key, and add interrupt signal handler in audio recording process

* feat: Check if the lock is stale when acquiring locks

* refactor: Convert database lock path to a constant in config file
