Refactor game logic into utility modules and add cross-device sync

Extracted game state management, share logic, and stats API calls into dedicated modules (game-persistence.svelte.ts, share.ts, stats-client.ts), and moved daily verse loading to client-side to fix timezone issues. Added a guesses column to daily_completions for cross-device state restoration for logged-in users, a new GET /api/stats endpoint, and a staging deploy script.
