fix(ui): New fields don’t automatically update completeness scoring UI

[afogel]

Closes #24

What changed:

• Use max_points from completeness_score.category_details when displaying per-category points and in the scoring explanation list.
• Add fixed table layout and column width rules for .category-table to stabilize column sizing and handle long content.

Why:

• Align the UI with dynamically calculated scoring rules rather than hard-coded point totals.
• Improve readability and consistency of table layout.

Testing:

• Not run (template change only).

Suggested next steps:

1. Quick manual UI check of the results page to confirm table layout and point totals render correctly. You can also review the deployed changes here: https://huggingface.co/spaces/ariel-pillar/OWASP-AIBOM-Generator
