fix: video/audio streaming instead of blob download

Videos and audio now stream directly via URL with auth token query
param instead of downloading entire file into a JS blob. Fixes
playback of large videos (170MB+ was timing out). Images still use
blob URLs. streamUrl() added to filebrowser client and cloud store.
