Download row actions were wired only as swipe actions, and
SwipeActionModifier has #if !os(iOS) overloads that return the view
unmodified, so macOS had no way to pause, resume or cancel a download.
The video context menu could not cover it either, since the .downloads
context deliberately hides the built-in cancel item.
Give active download rows their own context menu with pause when queued
or downloading, resume when paused, retry when failed, and a destructive
cancel. Right-click on macOS, long-press on iOS.
Completed rows had a related bug: the delete item called an onDelete
callback that DownloadsView never passed, so it rendered but did nothing
on macOS. Drop the callback and delete via the download manager directly,
which is what already made the same menu work in HomeView.

Proxied thumbnail URLs from Invidious/Piped/Yattee server expire over
time. Two paths were left holding stale URLs: the Video Info carousel
kept the original list copy even after fresh details arrived, and
downloaded videos rendered from the remote URL snapshot taken at
download time while the local thumbnail on disk was ignored.
Evict stale URLs from the Nuke cache when fresh video details load,
pass the fresh details through to the videoCard thumbnail, and resolve
downloads' thumbnails from the local file when localThumbnailPath is
set.
