refactor(auth): enforce team member authorization across app

Restrict sensitive operations to admins/owners and hide sensitive data
from team members:
- Add authorization checks to Livewire components and API endpoints
- Restrict team members from accessing sensitive permissions and data
- Hide environment variable values from non-admin team members
- Update policies to enforce team-level admin status requirement
- Add useSensitivePermissions policy for read:sensitive tokens
- Improve disabled button UX with auth-specific tooltips
- Add authorization checks in middleware for API tokens

Closes authorization gaps in project management, server management,
and settings components.
