Add Reset to Default buttons and improve system prompts with detailed tool usage instructions

- Added Reset to Default buttons for Actioner, Planner, and Coordinator prompts
- Completely rewrote default system prompts with comprehensive tool usage guides
- Actioner prompt now includes detailed examples, correct tool call formats, and common mistakes to avoid
- Added step-by-step workflow examples for common tasks (opening apps, clicking buttons, browser automation)
- Emphasized mandatory use of window handles for all keyboard/mouse operations
- Added visual formatting with emojis for better readability
- Planner prompt now includes iterative planning approach (one step at a time)
- Coordinator prompt updated with clearer routing guidelines
- All prompts now emphasize observation-first approach (CaptureWholeScreen before acting)
- Added static methods in ToolConfig to retrieve default prompts: GetDefaultActionerPrompt(), GetDefaultPlannerPrompt(), GetDefaultCoordinatorPrompt()

This should significantly improve the agents' ability to use tools correctly.
