feat: Add SHZ log inspection and HighGo database querying capabilities

- Introduced `inspect-shz-logs` skill for inspecting local and production logs with bounded read-only commands.
- Added `view.sh` script for log viewing with options for following logs and filtering by keywords.
- Created `query-shz-highgo` skill for querying the SHZ HighGo database through an SSH gateway.
- Implemented read-only SQL execution with strict controls on allowed statements and query structure.
- Added new domain and mapper classes for managing outdoor fair job associations.
- Enhanced `OutdoorFairController` to support job listing and management for outdoor fairs.
- Created SQL scripts for initializing outdoor fair job data and managing menu visibility.
