feat(build): add comprehensive ESBuild error handling to Vite configurations

- Add ESBuild logLevel: 'error' to all Vite configs
- Configure logOverride for critical errors: duplicate-export, duplicate-member, syntax-error, invalid-identifier
- Ensure builds fail immediately on ESBuild compilation errors
- Apply to common, web, and optimized Vite configurations

Prevents broken code from being deployed due to build-time errors
