feat: Add 5Why_ prefix to all database tables
- Rename all tables with 5Why_ prefix for namespace isolation - Update models: User.js, Analysis.js, AuditLog.js - Update routes: llmConfig.js - Update scripts: seed-test-users.js, add-deepseek-config.js, add-ollama-config.js - Add migrate-table-prefix.js script for database migration - Update db_schema.sql with new table names - Update views: 5Why_user_analysis_stats, 5Why_recent_analyses Tables renamed: - users -> 5Why_users - analyses -> 5Why_analyses - analysis_perspectives -> 5Why_analysis_perspectives - analysis_whys -> 5Why_analysis_whys - llm_configs -> 5Why_llm_configs - system_settings -> 5Why_system_settings - audit_logs -> 5Why_audit_logs - sessions -> 5Why_sessions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
