Implement unified Oracle mode support with auto-detection

- Unified Dockerfile with thick/thin mode auto-detection - Single docker-compose.yaml with build arguments - Auto-detect logic: thick mode for Oracle 10g/11g, thin mode for 12.1+ - Simplified .env configuration with clear mode selection - Updated admin.py with FORCE_THIN_MODE and INSTANTCLIENTPATH support - Added comprehensive documentation for both deployment modes - Container tested successfully with thick mode for Oracle 11g compatibility 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
