fix: resolve bugs and improve frontend performance

- Fix register not resetting isLoading on success (causing login page to hang) - Fix leaderboard streaks 400 error by forcing all_time timeframe - Reorder routes so static paths match before dynamic practice/:sheetId - Lazy-load QuestMap + Three.js (saves ~350KB gzip on initial load) - Move KaTeX CSS to lazy import (only loads on math pages) - Remove 28 duplicate Google Font @import lines from component CSS - Add font preconnect + single stylesheet link in index.html - Replace 8 unsafe JSON.parse(localStorage) calls with Zustand selectors - Add global ErrorBoundary to prevent full-app crashes - Extract arcTheme utilities to break static import cycle with QuestMap - Merge Three.js + Troika into single chunk to fix circular dependency Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
