Enhancment: Port voicedelay/voicewait functions from question arcs

Currently plain delay commands are used for the answer arcs when a delay is needed for a voice to finish playing out. I think currently the normal `delay` doesn't let you continue until the delay has expired. The voicedelay/voicewait allow you to click to force the line to complete (but not 100% sure/didn't test it yet).

I'm not sure it's worth porting it at this point, as doing so may break things. But it's worth noting this down anyway.

Look at the existing delay commands in the codebase, likely in script or audio handling modules. Compare with the voicedelay/voicewait functions from the question arcs to understand their behavior (allow clicking to skip). Test current delay behavior to confirm it blocks until expiration. Implementing this change may affect existing answer arc timing and user interaction.
