Tizen does not have offline caching — correct the baseline

The platform audit caught my own contract lying. I gave the Tizen baseline
offline.cache; Tizen caches only the playlist JSON (st_payload_cache, in
localStorage) and has no service worker and no media cache, so the bytes still
come from the network and an outage leaves a panel holding a playlist it cannot
play.

That is exactly the claim this model exists to prevent, made by the model itself,
and it would have applied to every legacy Tizen panel — the ones that declare
nothing and depend entirely on the baseline being honest.
