fix: improve E2E test reliability and fix openSettings helper

- Fixed openSettings helper to navigate directly to /settings page instead of clicking UI elements
- Updated permission prompt tests to expect 2 tool call badges in Always Ask mode
- Added timeout handling for permission denial scenarios
- Increased timeout for file creation verification in permission tests
- Fixed waitForAgentFinishUI to handle agent states after permission denial

These changes improved test pass rate from 11/21 to 13/21 tests passing.
