Make family names clickable links with acronyms in viewer

Update the NIST viewer dashboard to make family names in the
"Coverage by Control Family" section clickable links that navigate
to the family detail page. Also add the family acronym in parentheses
for clarity.

Changes:
- Family names now link to family.html?family=<family_id>
- Added acronym in parentheses, e.g., "Access Control (AC)"
- Link styled in blue (#0366d6) to indicate interactivity
- Clicking a family name navigates to the family-specific view

Example: "Access Control" → "Access Control (AC)" (clickable)

This improves navigation and makes it easier to understand the
relationship between full family names and their abbreviations.
