Add comprehensive multi-tenant architecture upgrade plan

Browse Source

Creates detailed 60-page implementation roadmap for transforming ROA2WEB from
single-tenant to multi-tenant SaaS architecture. Plan includes 6 phases with
backward compatibility, hybrid connection support (SSH tunnel + direct), and
complete deployment strategies for dev/Docker/Windows environments.

Key features:
- Tenant isolation with separate Oracle connection pools per tenant
- Dynamic SSH tunnel management with auto-restart
- Encrypted credentials in PostgreSQL/SQLite tenant config DB
- JWT-based tenant identification and access validation
- Redis cache namespacing per tenant
- Comprehensive testing and migration strategies

Timeline: 14-20 days implementation
Target: <10% performance overhead, zero downtime migration
