docs: artifact field change activity with before/after values [sc-16552]

[cachafla]

Pull Request Description

Shortcut: https://app.shortcut.com/validmind/story/16552
Implementation: validmind/backend#3313, validmind/frontend#2675

What and why?

[sc-16552] shipped artifact Activity parity: artifact custom field edits now emit updated-field events with before/after values, shown on the artifact Activity tab, in a per-field change history popover ({{< fa clock >}} on hover), and filterable on record Activity via a new Artifact Fields event category. Restricted artifact fields are hidden from activity for users without access. None of this was documented.

Before: Docs only mentioned coarse "Artifacts added, updated, or removed" on record activity; no artifact-scoped activity coverage at all.
After:

• guide/validation/update-artifacts.qmd — new View artifact activity section: the Activity tab, View Details before/after expansion, per-field change history on hover, and the permission-redaction limitation.
• guide/reporting/view-record-activity.qmd — Artifact Fields added to both the Event Category and Filter by Value tabsets, with footnotes to the new section.
• guide/reporting/_view-record-activity-overview.qmd (shared include) — added artifact field changes with before/after values to what record activity tracks.

Pages to review

Updated content appears on these rendered pages (hosted preview, validate ✅):

Page	What changed
Update artifacts → View artifact activity	New section: Activity tab, View Details before/after values, per-field change history, permission redaction callout
View record activity → Filter record activity	Artifact Fields added to both the Event Category and Filter by Value tabsets
View record activity → What is tracked	Overview include now lists artifact field changes with before/after values
Training: Developer Fundamentals — Finalizing documentation	Slide consuming the updated shared include
Training: Administrator Fundamentals — Organizational oversight	Slide consuming the updated shared include
Training: Validator Fundamentals — Finalizing validation reports	Slide consuming the updated shared include

How to test

skills/validmind-docs-coverage/scripts/render-pages.sh \
  guide/reporting/view-record-activity.qmd \
  guide/validation/update-artifacts.qmd \
  training/developer-fundamentals/finalizing-documentation.qmd \
  training/administrator-fundamentals/organizational-oversight-reporting.qmd \
  training/validator-fundamentals/finalizing-validation-reports.qmd

All five pages (the two guides plus the three training consumers of the shared include) render cleanly. The only warning (Unable to resolve link target: validmind/validmind.qmd in the validator training deck) is pre-existing and unrelated to these lines.

What needs special review?

• UI wording is taken from the merged frontend implementation (tab names, View Details, clock icon on field hover). Worth a quick sanity check against the live app.
• Placement of the new section in update-artifacts.qmd (between commenting and tracking resolution).

Dependencies, breaking changes, and deployment notes

None. Docs-only.

Release notes

Artifact field changes are now fully auditable: view before and after values on the artifact Activity tab, hover over any artifact field to see its change history, and filter record activity by the new Artifact Fields category. Learn more ...
