fix: prevent profile tooltips from opening on keyboard focus

  Resolves accessibility issue where profile cards automatically opened
  popup tooltips when receiving keyboard focus, violating WCAG 2.1 guidelines.

  - Add trigger: 'mouseenter' to ProfileTooltip to prevent focus-triggered popups
  - Add keyboard navigation (Enter/Space) to open full profile pages
  - Add proper ARIA attributes for screen readers

  Fixes #1949
