fix: job application page is now visible

[raizasafeel]

Summary

• The Job Applications page was not rendering due to createListResource asking for dotted-field joins (user.full_name as full_name, etc.) on LMS Job Application, which upstream frappe.client.get_list no longer supports.
• Turned it to 2 queries:
  1. fetch applications first
  2. fetch the matching users via a whitelisted helper.

Note: Temp workaround until framework restores dotted joins (going to be reverted)
