feat: add RoleDetail read-only view with affiliations, members, and moderators

[herpaderpaldent]

Summary

Implements the RoleDetail page — a read-only detail view for ACL roles, showing:

• Role metadata (name, type badge)
• Affiliations — corporations/alliances/characters the role applies to, with affiliation type
• Moderators — users who can moderate the role
• Members — full membership list with status badge (active/inactive/pending)

Changes

Backend

• ShowControlGroupController — eager-loads role_memberships.entity.main_character; now passes role.members (all user memberships with status/can_moderate/user) and role.moderators (users with can_moderate=true)
• ShowControlGroupControllerTest — asserts role.members and role.moderators are present in the Inertia response

Frontend

• resources/js/Pages/AccessControl/RoleDetail.vue — full read-only detail page (replaces 13-line stub)
  • Uses PageHeader, EntityByIdBlock, EntityBlock, EveImage from Shared
  • Wayfinder-generated routes for navigation

Depends on

PR #1485 (Wayfinder migration) must merge first.

PR Summary

• Improved Role Details Display: We've made major updates to the Role Detail view to make it more informative and easier to use. Now it's more structured and provides a better user experience. Users who have edit permissions can now also edit the PageHeader link directly.
• Enhancements to Backend Operations: We've made changes in the backend process to gather more data which involves including role_memberships.entity.main_character for moderators and members. Also, the way we map user memberships has been updated, which now separates them into members and moderators for more clarity.
• Advanced Unit Testing: To ensure the new added functionalities are performing as expected, we have updated our unit tests. These tests now also check whether the correct members and moderators arrays are included in the role objects.
