refactor: convert endpoint speed test to modal dialog

- Transform EndpointSpeedTest component into a modal dialog
- Add "Advanced" button next to base URL input to open modal
- Support ESC key and backdrop click to close modal
- Apply Linear design principles: minimal styling, clean layout
- Remove unused showBaseUrlInput variable
- Implement same modal pattern for both Claude and Codex
