fix(ux): improve empty-state messaging for tickets #49 and #57

#49 — upgrade MyVacationsClient account-not-linked inline text to a
prominent centred amber card with icon, heading, and admin-action guidance.

#57 — replace vague AI suggestions hint with actionable copy explaining
the Step 3 dependency before the user wonders why the list is empty.
