fix: translate all remaining English UI strings to Chinese and remove dead code

- Translate approval_action_card (Approve/Reject/Cancel/Expired)
- Translate tool_execution_card status labels (Executing/Completed/Error)
- Translate chat_providers error messages and stream content
- Translate message_bubble "Thinking..." indicator
- Translate terminal page tooltips (Reconnect/Disconnect)
- Translate fallback values (Untitled/Unknown/No message) across all pages
- Translate auth error "Login failed" and stream error messages
- Remove dead voice_providers.dart (used speech_to_text which is not installed)
- Remove dead voice_input_button.dart (not referenced anywhere)
- Fix widget_test.dart (was referencing non-existent MyApp class)
