Fix file upload limits and UI performance issues

- Remove artificial 18MB file size restrictions across all layers - Increase limits to industry standard: 5GB for file operations, 1GB for JSON - Eliminate duplicate resize handlers causing UI instability - Fix Terminal connection blank screen by removing 300ms delay - Optimize clipboard state flow for copy/paste functionality - Complete i18n implementation removing hardcoded strings - Apply Linus principle: eliminate complexity, fix data structure issues 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
