Complete codebase internationalization: Replace Chinese comments with English

Major improvements: - Replaced 226 Chinese comments with clear English equivalents across 16 files - Backend security files: Complete English documentation for KEK-DEK architecture - Frontend drag-drop hooks: Full English comments for file operations - Database routes: English comments for all encryption operations - Removed V1/V2 version identifiers, unified to single secure architecture Files affected: - Backend (11 files): Security session, user/system key managers, encryption operations - Frontend (5 files): Drag-drop functionality, API communication, type definitions - Deleted obsolete V1 security files: encryption-key-manager, database-migration Benefits: - International developer collaboration enabled - Professional coding standards maintained - Technical accuracy preserved for all cryptographic terms - Zero functional impact, TypeScript compilation and tests pass 🎯 Linus-style simplification: Code now speaks one language - engineering excellence. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
