The Expiry column header now has a master expiry selector with a 🔓/🔒 toggle. Locking it snaps every leg to the most common expiry, then any change to the master propagates to all legs (each re-priced from its new expiry's chain). Per-leg expiry selects are disabled while locked. Lock resets when switching symbols or clearing. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
