This pull request introduces a new "owner" concept to the system, allowing for the designation of a specific administrative user as the owner of the installation. It adds support for managing ownership, including validation rules, configuration changes, and UI updates. Additionally, it enhances user management by introducing a may_administrate permission for more granular control over administrative rights.

Ownership Management

• Added a new configuration key owner_id in the configs table to track the owner of the installation, along with a migration to initialize this value based on existing administrators (database/migrations/2025_06_29_080951_create_owner.php).
• Introduced OwnerConfigRule to restrict changes to the owner_id configuration to the current owner only (app/Rules/OwnerConfigRule.php).
• Added OwnerIdRule to enforce that only the owner can perform specific actions, such as deleting or modifying the owner account (app/Rules/OwnerIdRule.php).

Administrative Permissions

• Introduced a new may_administrate permission for users, allowing fine-grained control over administrative capabilities in user creation and update workflows (app/Actions/User/Create.php, app/Actions/User/Save.php). [1] [2]
• Updated user-related request classes (AddUserRequest, SetUserSettingsRequest) to handle the may_administrate attribute, including validation and processing (app/Http/Requests/UserManagement/AddUserRequest.php, app/Http/Requests/UserManagement/SetUserSettingsRequest.php). [1] [2]

Frontend Updates

• Added a checkbox in the user creation/edit form to toggle the may_administrate permission, with a warning icon and special styling to indicate the significance of this permission (resources/js/components/forms/users/CreateEditUser.vue).

Additional Enhancements

• Extended the UserManagementResource to include an is_owner field, which identifies if a user is the owner of the installation (app/Http/Resources/Models/UserManagementResource.php).
• Updated the Configs model to validate the owner_id value against existing administrative users (app/Models/Configs.php).
