fix: resolve TypeScript build errors and deployment blockers

- Fix missing lucide-react icon imports in type declarations
  - Add 40+ missing icon exports (Loader2, ExternalLink, Type, etc.)
  - Fix ArrowLeft → ChevronLeft imports in auth pages
  - Resolve LucideIcon type declaration issue

- Fix invalid Button variant 'ghost' → 'text' in KeyboardShortcutsHelp

- Ensure project builds successfully with Bun package manager
- Address CodeRabbit review feedback for production readiness

These fixes resolve all TypeScript compilation errors and make the
project fully deployment-ready. Build now passes with zero errors.
