Opening Plezy on a TV box resumes the resident process rather than
cold-starting it, so the Libraries grid kept showing the in-memory
content from the previous session -- hours stale -- until the user
switched libraries and back. Nothing on the resume path refreshed tab
content.
MainScreen now latches genuine backgrounding and, on a resume more than
five minutes later, refreshes LibrariesProvider and sweeps the content
tabs through each screen's in-place Refreshable.refresh() -- skipped
while offline, before startup priming, during playback, or with no
connected servers. LibrariesScreen.refresh() now refetches the selected
library's loaded tabs (the toolbar refresh action) instead of
re-selecting the saved library, which never reloaded them because tab
widgets only reload when the library's globalKey changes.
