docs: Update ROADMAP.md to reflect completed priorities and current project status

[X9X0]

Summary

Updated the project roadmap to accurately reflect current development status after comprehensive codebase review. Discovered that all three planned short-term priorities (mock equipment, server discovery, mobile app) are already complete.

Changes Made

Roadmap Updates

• ✅ Updated completion status for immediate priorities (Q4 2025)
• ✅ Documented mock equipment drivers as complete (Pre v1.0.0)
• ✅ Documented server discovery (mDNS/Bonjour) as complete (Pre v1.0.0)
• ✅ Documented mobile app v1.1.0 MVP as complete (November 15, 2025)
• ✅ Identified actual next priorities (v1.1.1, v1.2.0, equipment panels)

Completed Features Documented

1. Mock Equipment Drivers (COMPLETE - Pre v1.0.0)

• MockOscilloscope with realistic waveforms - 376 lines
• MockPowerSupply with CV/CC modes - 264 lines
• MockElectronicLoad with thermal simulation - 349 lines
• Complete documentation: docs/MOCK_EQUIPMENT.md

2. Server Discovery (COMPLETE - Pre v1.0.0)

• Server-side mDNS broadcasting (server/utils/mdns.py)
• Client-side discovery (client/utils/mdns_discovery.py)
• GUI discovery dialog (client/ui/discovery_dialog.py)
• Complete documentation: docs/MDNS_DISCOVERY.md

3. Mobile App v1.1.0 MVP (COMPLETE - November 15, 2025)

• ~2,700 lines TypeScript (React Native + Expo)
• Full authentication (username/password, MFA, biometric)
• Equipment management with real-time WebSocket updates
• Alarms monitoring and acknowledgment
• Settings and server configuration
• Documentation: mobile/README.md, mobile/DEVELOPMENT.md

Next Priorities Identified

1. Mobile App v1.1.1 - Push notifications, deep linking (1-2 weeks)
2. Advanced Visualization v1.2.0 - 3D plots, FFT waterfall (2-3 weeks)
3. Equipment-Specific Control Panels - Professional UX (50-60 hours)
4. Enhanced Testing & Documentation - 80%+ coverage (20-30 hours)
5. Enterprise Features v1.3.0 - SAML, LDAP, FIDO2 (2-3 weeks)

Impact
