feat: surface Langflow error messages to users#9

Conversation
…n encryption key Replace generic "Sorry, an error occurred" with actual error messages from Langflow and the backend. Preserve partial streamed content when errors occur mid-stream. Use PatternFly Alert error prop and extraContent for clean rendering with retry support. Also auto-generate TOKEN_ENCRYPTION_KEY for local dev so OAuth integrations work without manual configuration, and default .env.example to development mode with OAuth enabled.
