Add multiple Playwright YAML configuration files for session management UI

- Created new YAML files for Playwright that define the structure and components of the session management UI.
- Each file includes configurations for toolbars, buttons, alerts, and other UI elements.
- The configurations support various actions such as finding sessions, filtering sessions, and customizing settings.
- Added support for user interactions with buttons for navigating, signing in, and managing agent sessions.
- Ensured consistent structure across all YAML files for maintainability and ease of updates.
