fix(entcms): 重写所有数据库操作使用 async with context manager

_get_db() 返回的是 async context manager，不是 sor 对象。
所有函数都错误地直接调用 sor.R/C/U/D，导致 AttributeError。

修正为正确模式：
  db = DBPools()
  async with db.sqlorContext(DBNAME) as sor:
      await sor.R('table', ns)

影响函数：
- cms_content CRUD (4个)
- cms_categories CRUD (4个) + get_category_options
- cms_leads CRUD (4个) + submit_lead
- cms_sections CRUD (4个) + get_visible_sections
- cms_site_config CRUD (4个) + get_site_config
- get_published_content, get_latest_news, get_content_detail
- submit_content_for_approval
