pub type ApolloTokens = (String, Option<String>, i64);Expand description
Tokens as the rest of apollo expects them: (access, refresh, expires_at)
with expires_at in milliseconds.
rs_ai_oauth stores expires_at in seconds; apollo’s OAuthTokenCache
compares against chrono::Utc::now().timestamp_millis(). Converting here
keeps the unit mismatch in one place instead of every call site.
