[BUG] Approval prompt hidden when tool detail view (Ctrl+O) is expanded

Bug description

When a tool call is running and you expand the detail view with Ctrl+O, any approval prompt for a subsequent tool call appears behind the expanded view and is never visible. The tool sits in \"Waiting\" state with no way to approve or deny it without knowing to close the expanded view first.

Steps to reproduce

1. Trigger a tool call that requires approval
2. While it's running, press Ctrl+O to open the expanded detail view
3. The tool completes and Claude queues another tool call requiring approval
4. The approval prompt never appears — the expanded view obscures it
5. Tool stays in \"Waiting\" state indefinitely

Expected behavior

Approval prompts should surface on top of / outside the expanded detail view, or the expanded view should close/pause when an approval is needed.

Workaround

Close the expanded view (Escape) before a tool finishes to avoid missing the prompt.
