🟠 [RGAA 11.5] Related form fields not properly grouped

[jbpenrath]

Bug Report

Problematic behavior
Related form fields are not grouped with <fieldset>/<legend>. Specifically, the "Read" / "Unread" radio buttons in the search filters are not grouped.

Expected behavior/code
Related fields (radio buttons, checkboxes sharing a common purpose) must be wrapped in <fieldset> with a <legend> describing the group.

Steps to Reproduce

1. Open search filters
2. Use a screen reader to navigate to the "Read" / "Unread" fields — no group label is announced

Environment

• RGAA Criterion: 11.5
• Severity: 🟠 Major

Possible Solution
Group "Read" / "Unread" with <fieldset>/<legend> (legend: "Read status").
