The Album showed durations like -36:35, -136:23 and 545:26 on a Mavic
Pro's photos. MediaItem.durationLabel only checked for null, but the
SDK fills durationInSeconds for every file, so stills carry junk that
was formatted straight into a badge.
Require isVideo and a positive duration. Stills now get no badge and
nonsense values are rejected; real clips are unaffected. Display-only —
durationLabel renders in one place and nothing else reads it.
Pre-existing, unrelated to the identity work; spotted while testing the
Album against a real aircraft.
