fix prevent duplicate role badges

[LrxGaelle]

Description

This PR fixes an issue where multiple role badges could be displayed for the same user (e.g. Space Admin and Space User at the same time).
The role badge resolution has been simplified by centralizing the decision logic into a single computed property, ensuring that only one badge is displayed according to the user's effective role.

Changes

• Fix duplicate role badge display.
• Refactor UserRoleBadge to compute a single badgeKey.
• Remove redundant role prop from UserRoleBadge.
• Simplify UserCard by passing only the required role information (cloudRole, projectRole, isSpaceRole).
