feat(kb): Add Change Tracker KB articles — batch 2b

[hilram7]

Summary

• Adds 9 new Change Tracker KB articles
• Retires 1 article (change-db-location-windows) — near-duplicate of existing 8.2 product doc

Changes

• Migrated 9 configuration, database, audit, and troubleshooting articles from staging repo
• Applied SME feedback: terminology alignment in fileaccessed-events (Configuration Templates → Policy Templates, Device Templates → Policy Templates, Groups → Device Groups), Tracked Attributes dropdown text corrected
• Retired change-db-location-windows.md — SME confirmed it's a near-duplicate of the 8.2 product doc at databasecustompathwindows.
• Removed all kb.netwrix.com/#### Related links and dropped broken attachments
• Fixed truncated frontmatter, typos, mojibake encoding, and copy/paste errors
• Structural improvements: added Cause section to mongodump-binary-not-found, condensed verbose notes in mongodb-out-of-memory, deduplicated repeated NOTE in fileaccessed-events, split awkward steps in object-reference-error-groups-page, converted question-style steps to imperatives

Known Gaps — SME Review Needed

• express-agent-database-log-location.md — Article is thin (the source KB body only had the config snippet, though broken screenshot attachments suggested a fuller procedure). Please decide:
  1. EXPAND (add Overview + full numbered steps for stop service, backup, edit, restart, verify)
  2. RETIRE
• mongodump-socket-buffer-error.md — Article is very thin (essentially a pointer to a Microsoft article). Please confirm whether additional content should be added, or if the pointer format is acceptable.
• object-reference-error-groups-page.md — Article body says "Settings > Groups" throughout. Ben confirmed the fileaccessed-events UI uses "Device Groups" — please verify whether the Groups page in this article should also be labeled "Device Groups" in the 8.2 UI. If so, the title, error message, and body should all be updated together for consistency.
• mongodb-out-of-memory.md — Log timestamp example is from 2017 (cosmetic but looks dated). Please decide whether to update to a more recent example.

Note on Missing Screenshots

The original screenshots for these articles are no longer accessible (broken CDN links). During migration, inline image references were replaced with HTML comment placeholders like:

<!-- Image removed: [description of what the screenshot showed] -->

Choose one of the following options:

1. Add fresh 8.2 screenshots — grab current UI screenshots to replace the placeholders
2. Confirm no image needed — the procedure is followable without a visual; placeholder can be removed

Articles with placeholders in this PR:

• fileaccessed-events.md
• upload-compliance-template.md
• mongodb-out-of-memory.md
• mongodump-binary-not-found.md
• planned-changes-report.md
• object-reference-error-groups-page.md

Testing

• Vale: 0 errors, 0 warnings on all modified files
• Local build: successful, no broken links or anchor errors

Closes #1189
