feat(privacy): add Roleplay profile defaults to PrivacyDefaults

Adds RoleplayWhitelist (PrivacyFirst + Say + both emote types) and
RoleplayRetentionOverrides (Say 30d, emotes 90d). Shout/Yell and
Novice Network stay out — public-distance noise from strangers
is not story content. Whitelist + overrides are IReadOnlySet /
IReadOnlyDictionary with pure-helper type footprint, so the Build
Suite can pin them without touching Dalamud.
