Fix remaining E2E test failures

- Fixed permission-prompt deny test to expect 1 tool call badge instead of 2
- Added timing fix to agent-details-sheet test to wait for agent response

This brings the E2E test suite to 20/21 passing tests. Only the checkout-ship
test remains failing due to complex UI interaction issues with worktree selection.
