feat: can now select if you want to see synthesized audio in the paradigm layouts

[nienna73]

What's in this PR:

• add the setting for seeing synth audio in paradigm layouts
• add UI for this setting
• add the behaviour for this setting

NOTES: I tried to make it so this option would only appear when "Show Paradigm Audio" was set to "yes", but that required a page reload, which interfered with the toast signalling that the setting was saved. I decided the toast was more important than the reload, so instead I added a note to the description this new setting.
