Fix notification badge sticking after "Mark read"

The badge counted ALL actionable crew items (invites, join requests,
pending confirmations) regardless of read state, so "Mark read" (and even
opening the bell) never cleared it. Now the badge counts only items newer
than a per-account "seen at" timestamp that "Mark read"/open updates.
Actionable crew cards still render in their tab until acted upon — only
the red badge clears — which is the expected behavior.
