LeaderboardResource was a tuple struct of Option<Vec<Entry>>: None for
pre-fetch and empty Vec for both "actually empty" and "fetch failed"
— the user couldn't tell a network error from a legitimately quiet
leaderboard. The resource is now a four-state enum (Idle / Error /
Loaded), with Loaded covering both populated and empty rows. A
transient error no longer wipes a previously populated list, and the
panel renders "Couldn't reach the leaderboard. Try again later."
when the most recent fetch failed.
The Opt In / Opt Out buttons used to render unconditionally and
silently no-op under LocalOnlyProvider. The panel now reads the
SyncProviderResource backend name and, when no remote is configured,
replaces the buttons with a single line directing the player to
configure cloud sync in Settings.
