feat(settings): collapse Discord sub-options under one header

"Fetch covers from Apple Music" and "Custom text templates" are now both
tucked into a single collapsible "Advanced Discord options" block (default
collapsed) that only appears when Discord Rich Presence is enabled.
Reduces vertical noise in Settings → General for the common case where
users just flip Rich Presence on and leave the defaults.

Uses the same chevron-rotate pattern as the font picker and contributors
list. Adds `settings.discordOptions` key in all 8 locales.
