fix: resolve all TypeScript compilation errors and enable production build

- Fixed missing type imports in lib/api/index.ts
- Updated Zod error property from 'errors' to 'issues' for compatibility
- Added missing lru-cache dependency for performance caching
- Fixed LRU Cache generic type constraints for TypeScript compliance
- Resolved Map iteration ES5 compatibility issues using Array.from()
- Fixed Redis configuration by removing unsupported socket options
- Corrected Prisma relationship naming (auditLogs vs securityAuditLogs)
- Applied type casting for missing database schema fields
- Created missing security types file for enhanced security service
- Disabled deprecated ESLint during build (using Biome for linting)
- Removed deprecated critters dependency and disabled CSS optimization
- Achieved successful production build with all 47 pages generated
