 * Rules under test:
 *  1. User + location in the same company → allowed.
 *  2. User in company A, location in company B → rejected.
 *  3. Location with no company + floater ON → allowed.
 *  4. Location with no company + floater OFF → rejected.
 *  5. No company selected for user → location company is irrelevant → allowed.
