fix: OAuth model restriction + ConversationPhase theme for light mode OAuth tokens (sk-ant-oat) can only use Haiku — restored the model restriction that was overwritten by the PKCE commit. Also migrated ConversationPhase from hardcoded dark-mode classes to CSS variable theme system so it's readable in light mode (default for new users).
