Critical Fix: Complete Node Activation & Reputation System Overhaul

CRITICAL ISSUE RESOLVED:
- Fixed Genesis node reputation system causing consensus exclusion
- Resolved node_id vs activation_code mismatch in reputation checking
- Eliminated critical code duplication across 4 files causing maintenance issues

ROOT CAUSE ANALYSIS:
1. Genesis nodes got 50% reputation instead of 90% due to:
   - node_id format: 'node_9876_2' (P2P identifier)
   - activation_code: 'QNET-BOOT-0001-STRAP' (Genesis code)
   - Reputation system was checking node_id == activation_code (NEVER matches!)

2. P2P system was overwriting reputation values:
   - node.rs set 90% for Genesis → unified_p2p.rs overwrote to 50%
   - Result: Genesis nodes excluded from consensus (50% < 70% threshold)

3. Critical code duplication across files:
   - Genesis constants duplicated in unified_p2p.rs, node.rs, bin/qnet-node.rs, quantum_crypto.rs
   - Risk of desynchronization and maintenance nightmare

COMPREHENSIVE FIXES IMPLEMENTED:

1. **Reputation System Overhaul**:
   - Fixed reputation detection logic to use QNET_BOOTSTRAP_ID environment variable
   - Genesis nodes: 90% reputation via bootstrap ID detection (not node_id matching)
   - Regular nodes: 70% reputation (default for production nodes)
   - Both types now participate in consensus (≥70% threshold met)

2. **Code Deduplication & Centralization**:
   - Created genesis_constants.rs module for all Genesis-related constants
   - Centralized GENESIS_BOOTSTRAP_CODES, GENESIS_NODE_IPS, LEGACY_GENESIS_NODES
   - Eliminated duplication across multiple files
   - Added utility functions for Genesis node management

3. **Enhanced Docker/Container Support**:
   - Added get_external_ip() function with multiple IP detection services
   - Improved QNET_MANUAL_IP support for explicit IP specification
   - Better fallback logic for containerized environments
   - Enhanced IP validation for Genesis node authorization

4. **Genesis Node Logic Improvements**:
   - Fixed Genesis node duplication detection (only blocks same ID, not all Genesis nodes)
   - Added smart IP mapping for all 5 Genesis nodes (001-005)
   - Improved Docker IP detection to prevent self-blocking
   - Enhanced security while maintaining functionality

BEHAVIORAL CHANGES:
- Genesis nodes: ✅ Now get 90% reputation and participate in consensus
- Regular nodes: ✅ Continue to get 70% reputation and participate in consensus
- Docker environments: ✅ Improved IP detection and Genesis node startup
- Code maintenance: ✅ Centralized constants reduce duplication errors

PRODUCTION IMPACT:
- Fixes critical issue preventing Genesis nodes from consensus participation
- Ensures stable network initialization with all 5 Genesis nodes
- Improves maintainability through code centralization
- Enhanced Docker/container deployment reliability

TESTING VERIFICATION:
- Genesis activation flow: ✅ 90% reputation → consensus participation
- Regular activation flow: ✅ 70% reputation → consensus participation
- Format validation: ✅ Proper validation for both Genesis and regular codes
- No conflicts: ✅ Genesis and regular node logic work independently

This resolves critical network stability issues and ensures proper
reputation-based consensus participation for all node types.
