Play a sound on notifications
This issue requests playing a sound on certain notifications, specifically:

- when an offer is accepted
- when the peer confirms payment is sent
- when the peer confirms payment is received

Additionally, an option should be added to Settings > Preferences > General preferences, e.g. "Play sounds on key events".

The sounds should only be played when running the desktop app, not the daemon.

Here are 2 sound files: [haveno_sounds.zip](https://github.com/user-attachments/files/17150957/haveno_sounds.zip)

We're thinking to play the chime when an offer is taken and when the peer confirms payment sent, and then play the cash register sound any time funds are received to your main wallet (this will cover when trades complete).

The code is already importing an audio file, core/src/main/resources/prevent-app-nap-silent-sound.aiff, used within [AvoidStandbyModeService.java](https://github.com/haveno-dex/haveno/blob/11c0f7613ba1aa28c90d2dda479700ac316612aa/core/src/main/java/haveno/core/app/AvoidStandbyModeService.java#L165), so the implementation can refer to that.
