YT/NewPipe-style — when ResumePositionsStore has an entry for a
video, paint a 3dp red bar across the bottom of the thumbnail
showing position/duration. Reads instantly as "you started this."
Consolidated the duplicate thumbnail render logic across 6 row
sites (FeedRow, RecentRow, ResultRow, ChannelVideoRow, RelatedRow,
PlaylistsScreen) into a single feature/player/VideoThumbnail
composable. Includes the existing duration-pill overlay + the new
progress bar. ThumbnailProgressOverlay is a BoxScope extension so
custom thumbnail compositions can drop it in without going through
the full helper.
