Dashboard: include L4/L5 skip in single-badge precedence

The previous single-badge logic only considered skip at L3 and xfail
at L2-L5, which meant L4/L5 skip statuses (the dominant skip
population — many models have YAML cases marked skip_reason) showed
no badge at all.

Replace the if/else cascade with a loop that walks L5 → L2 and emits
the first xfail OR skip encountered. Both exception kinds are now
reportable at every level where the data model permits them.
