Pick tracking, watchlist & locks

A full pick-tracking workflow arrived — watchlist, locks, and a personal lock-history page — plus clearer navigation and legal pages.

• A clear flow for following players: browse the slate, add to a watchlist, and lock in your picks, with watch and lock buttons across the slate, player pages, and matchup tables.
• A "My Lock History" page: total picks, hit rate, a rolling performance chart, most-locked players, and a day-by-day history.
• A rebuilt "My Batters" page split into today's locks, your watchlist, and system-flagged players.
• Reorganized navigation into clearer groupings, plus Privacy and Terms pages, a site footer, and one-click unsubscribe in every email.
