Clerk's short-lived JWTs (60s) can expire when browser tabs are
backgrounded and the SDK's refresh interval is throttled. This left
users silently logged out — actions returned 401s shown as generic
error toasts with no recovery path.
Prevention: refresh the Clerk JWT on tab visibility change so the
token is always fresh when the user returns from a backgrounded tab.
Detection: replace all 12 raw fetch() calls with an authFetch wrapper
that catches 401 responses and sets an authDegraded state, triggering
a blocking recovery overlay instead of confusing toasts.
Recovery: AuthRecoveryOverlay (mirrors ConnectionOverlay pattern)
prompts the user to reload the page, which re-authenticates via
Clerk's long-lived session cookie.
Also adds missing try/catch to handleStartDraft, handleMakePick,
handleForceAutopick, handleForceManualPick, and handleReplacePick
which previously had no network error handling.
