feat: enhance AI agent functionality with tool management and logging improvements

- Added AllowedToolCodes field to Context for managing tool access.
- Introduced ResumeSource in aiReplyTraceData to track resume points.
- Enhanced logging with additional fields: PlannedSkillName, SkillRouteTrace, InterruptType, ResumeSource, and FinalStatus.
- Implemented functions to parse and resolve allowed tool codes for agents and skills.
- Refactored skill definition creation and update logic to streamline request handling.
- Updated MCP tool catalog to include source type and integrated built-in tools.
- Improved UI components to display additional tool information and enhance user experience.
