Fix Setup app missing navigation by loading SetupPlugin before contributor plugins

[Claude]

Setup app returned empty navigation areas despite plugins registering menu items via setupNav.contribute(). The service contribution pattern requires the provider plugin to initialize before consumers.

Changes

• apps/studio/server/index.ts: Moved SetupPlugin initialization before AuthPlugin, SecurityPlugin, AuditPlugin, and AIServicePlugin
• apps/studio/src/mocks/createKernel.ts: Applied same plugin ordering fix for test/mock environments

Context

The SetupPlugin registers a setupNav service during init() that other plugins consume to contribute navigation items:

// SetupPlugin.init()
ctx.registerService('setupNav', {
  contribute: (contribution: SetupNavContribution): void => {
    this.contributions.push(contribution);
  },
});

// AuthPlugin.init() - requires setupNav service to exist
const setupNav = ctx.getService('setupNav');
setupNav.contribute({
  areaId: 'area_administration',
  items: [{ id: 'nav_users', type: 'object', label: 'Users', objectName: 'user' }],
});

When SetupPlugin loaded last, the service didn't exist during other plugins' init() phase, causing all contributions to silently fail.

Result

Setup app now displays navigation across all areas:

• Administration: Users, Organizations, Teams, API Keys, Sessions, Roles, Permission Sets
• System: Audit Logs
• AI: Conversations, Messages
