{{--
    Subscription / trial expiration banner.

    Surfaces a warning at the top of every authenticated tenant page so the
    clinic owner cannot miss an upcoming lapse. The banner has three modes:

      - past         : already expired (a grace day before auto-suspension)
      - urgent       : <= 3 days left
      - approaching  : <= 14 days for subscription, <= 7 days for trial

    Hidden entirely when no clinic is in scope (guest pages) or when the
    runway is comfortable.
