fix(workflows): normalize report formatting in output templates

[Copilot]

Output format templates in several reporting workflows used ##/# headers and lacked <details> progressive disclosure, contradicting the guidelines in shared/reporting.md and causing inconsistent AI-generated output.

Changes

• weekly-safe-outputs-spec-review.md — Fixed last remaining ## Related Files → ### Related Files inside the PR body code block template
• daily-news.md — Wrapped chart embed sections in <details> for progressive disclosure (was the only reporting workflow with zero <details> tags in its output template)
• weekly-editors-health-check.md — Wrapped editor status table in <details> in the PR body template

All other files listed in the issue had already been updated; these three had residual non-compliance.

Before / After (weekly-editors-health-check.md):

# Before
### Editor Health Report – <date>
| Editor | URL | Status | Preview |
|--------|-----|--------|---------|
...

# After
### Editor Health Report – <date>
<details>
<summary><b>Editor Status & Screenshots</b></summary>
