Feature: Run an accessibility audit

[Mosas2000]

Summary: Audit the app for keyboard flow, focus management, semantic markup, and screen-reader support.

Why it matters: Governance tools should be usable by more people, not only by mouse-first desktop users. Accessibility improvements also make the app more robust and easier to maintain.

Scope:

• Check focus order and focus trapping.
• Add missing labels, roles, and semantic structure.
• Fix the highest-impact accessibility problems first.

Acceptance notes:

• Core actions can be completed with a keyboard alone.
• Important controls are announced clearly by assistive tech.
• The audit results turn into a prioritized remediation list.
