feat: expand auto-lock options and reset timer on Nostr tab focus

Add 90-minute and 3-hour auto-lock options, rename "60 minutes" to
"1 hour". Reset the auto-lock timer whenever a tab with window.nostr
injected gains visibility — so actively browsing Nostr clients no
longer triggers unexpected lockouts.
