feat: add disabling temp video blocking (#206)

fixes #206. allows disabling temporarily blocking a file from being converted if repeated failures in an hour. especially useful for local deployments over a network where it may be served through HTTP rather than HTTPS, breaking video conversion due to the hashing code requiring a secure context.
