HMM GIMS v88.5 — JD v6 integration

Replaces the 23 active standardized JD PDFs with the user-approved v6 PDFs and includes 23 matching DOCX files under assets/job-descriptions/approved-word/.
Updates js/modules/jd-data.js PDF references to those approved files and corrects the staff display names for Baraka, Method and Saruni.
Preserves all existing GIMS modules, SQL, staff assignment IDs and financial data. No SQL migration required.

IMPORTANT: static PDFs are accessible by direct URL. Existing staff UI visibility is not server-side file authorization. Use private storage/signed URLs for confidentiality.

Install: back up current GIMS files, then deploy this ZIP as a full replacement of application files without altering database tables or credentials. Verify staff-to-JD assignments in the admin UI.
