[BUG] Auth token and base URL wiped after navigating to agents panel and back

What's Wrong?

When using a custom LiteLLM proxy (via ANTHROPIC_AUTH_TOKEN and ANTHROPIC_BASE_URL environment variables), navigating to the agents panel using the double-left-arrow shortcut and returning to the conversation causes the auth token and base URL to be lost.

Checking /status after returning shows both fields empty/reset.

What Should Happen?

Environment variables persist for the lifetime of the Claude Code process. Navigating between panels should not affect the active configuration.

2. Launch claude
3. Run /status — confirm auth token and base URL are correctly shown
4. Press the left arrow twice to open the agents panel
5. Navigate back to the conversation
6. Run /status again — auth token and base URL are now wiped
