feat(kol): support multiple platform hints with shared tag renderer

Turn the KOL prompt platform hint into a multi-select backed by the
media platforms API, persist hints as a 、-joined string, and add a
reusable KolPlatformTags component so manage/generate/package/template/
workspace views and the generate-task drawer all render the hints
consistently with truncation and overflow handling.

Also auto-select the first available subscription prompt in
GenerateTaskDrawer when switching to the subscription-prompt target so
users land on a usable option without an extra click.
