Display token status on vulnerability finding page

Problem to solve

Now that we are storing the validity status of detected tokens, we need somewhere to display them. In the experiment phase, we are currently looking to add that information to the vulnerability report and findings pages. This issue is focused on the vulnerability finding page.

Design

Implementation Plan

• Expose finding_token_status in vulnerabilities_helper.rb
• Add TokenStatus section to vulnerability_details.vue
• Add tooltip to vulnerability_details.vue
• Create a feature flag similar to: !184577 (diffs)
• Add tests
