Fix user resource tracking during onboarding

Issue: First user created during onboarding not tracked in billing system
Root cause: User created BEFORE company exists, so company_uuid is null
Solution: Create company FIRST, then set company_uuid before user creation

Flow before:
1. User::create() - no company_uuid
2. Company created
3. assignCompany() - sets company_uuid after creation

Flow after:
1. Company::create() - company exists first
2. Set company_uuid in attributes
3. User::create() - with company_uuid set
4. assignCompany() - maintains relationship

This ensures ResourceCreatedListener can track the first user properly
since it requires company_uuid to log usage to billing_resource_usage table.
