setInterval(loadNotifications, 60000) ran unconditionally regardless
of tab visibility, and failures retried at the same fixed 60s cadence
forever. Now skips polling while document.hidden, resumes immediately
via visibilitychange when the tab regains focus, and backs off
exponentially (capped at 5 min) on repeated fetch failures, resetting
to the normal 60s cadence on the next success.
