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
