feat(boss): add job detail adapter

Add `boss detail` command to fetch full job posting details using
securityId from search results.

Fields returned: job description, skills, welfare, boss info (name,
title, active time), company info (industry, scale, stage), address.

Tested with real API calls against multiple job postings.

Usage:
  opencli boss detail --security_id <id_from_search>
