chore: promote changelog [Unreleased] → [01.39.00]

New "Data Sanitization" fieldset on profile form with four options:
- Sanitize User Passwords: replaces all bcrypt hashes with invalid sentinel
- Preserve Super Admin: keeps Super Users group passwords intact
- Sanitize User Emails: replaces with user123@sanitized.example.com
- Clear Session Data: excludes #__session table data (default: on)

DatabaseDumper sanitizes rows inline during dump — both in-memory
and file-streaming paths. Super admin detection uses group_id=8
from #__user_usergroup_map with static caching.

Use cases: sharing backups, creating demo/staging sites, GDPR compliance.

Partial #129 (Part 2 — restore script password reset — tracked separately)
