<issue_title>docs: Consolidate validation reports into authoritative documentation</issue_title>
<issue_description>## 🎯 Objective
Consolidate multiple overlapping validation reports (DATABASE_VIEW_VALIDATION_REPORT.md, SQL_VALIDATION_REPORT.md, VALIDATION_REPORT.md, VALIDATION_SUMMARY.md) into the primary authoritative documentation files, eliminating redundancy and ensuring single source of truth.

📋 Background

The repository currently contains 4 separate validation report files totaling ~31KB that document overlapping information about database views, SQL queries, and OSINT data validation. This creates confusion about which document is authoritative and makes maintenance difficult.

Current Validation Reports:

• DATABASE_VIEW_VALIDATION_REPORT.md (3.4K) - View documentation validation snapshot
• SQL_VALIDATION_REPORT.md (5.4K) - SQL query validation
• VALIDATION_REPORT.md (12K) - General validation report
• VALIDATION_SUMMARY.md (11K) - Validation summary report

Main Documentation Files:

• DATABASE_VIEW_INTELLIGENCE_CATALOG.md - Complete catalog of 84 database views (100% coverage verified 2025-11-25)
• DATA_ANALYSIS_INTOP_OSINT.md - Analysis frameworks with verified metrics
• service.data.impl/README-SCHEMA-MAINTENANCE.md - Schema maintenance guide

📊 Current State (Measured Metrics)

• Validation report files: 4 documents, 31KB total
• Overlap: ~70% redundant information across files
• Last validation date: 2025-11-25 (per DATABASE_VIEW_INTELLIGENCE_CATALOG.md)
• View documentation coverage: 100% (84/84 views)
• Database health score: >80/100 (per README-SCHEMA-MAINTENANCE.md)

✅ Acceptance Criteria

• All valuable validation metrics extracted from temporary reports
• Validation summary section added to DATABASE_VIEW_INTELLIGENCE_CATALOG.md
• SQL validation procedures documented in README-SCHEMA-MAINTENANCE.md
• Cross-references updated in all affected documentation
• 4 temporary validation report files removed from repository root
• Validation history preserved in git commit messages
• Documentation clearly states "Last Validated" dates for key metrics
• No loss of important validation procedures or findings

🛠️ Implementation Guidance

Files to Modify:

1. DATABASE_VIEW_INTELLIGENCE_CATALOG.md - Add "Validation History" section
2. service.data.impl/README-SCHEMA-MAINTENANCE.md - Expand validation procedures section
3. DATA_ANALYSIS_INTOP_OSINT.md - Ensure metrics aligned with validation results

Files to Remove:

1. DATABASE_VIEW_VALIDATION_REPORT.md - Integrate into DATABASE_VIEW_INTELLIGENCE_CATALOG.md
2. SQL_VALIDATION_REPORT.md - Integrate into README-SCHEMA-MAINTENANCE.md
3. VALIDATION_REPORT.md - Distribute key findings to appropriate docs
4. VALIDATION_SUMMARY.md - Merge summary into main documentation

Approach:

1. Extract all unique validation metrics and procedures from temporary reports
2. Add "Validation History" section to DATABASE_VIEW_INTELLIGENCE_CATALOG.md with:
   • Last validation date
   • Validation method
   • Coverage metrics
   • Health scores
3. Enhance README-SCHEMA-MAINTENANCE.md with:
   • SQL validation procedures
   • Health check interpretation guide
   • Validation scheduling recommendations
4. Update cross-references in all data product documentation
5. Remove temporary validation files
6. Update README.md intelligence documentation section

Example Structure for DATABASE_VIEW_INTELLIGENCE_CATALOG.md:

## 📊 Validation History

**Last Validated**: 2025-11-25  
**Validation Method**: Automated schema validation via validate-view-documentation.sh  
**Schema Source**: service.data.impl/src/main/resources/full_schema.sql  
**Coverage**: 100% (84/84 views documented)  
**Health Score**: 82/100 (per schema-health-check.sql)

**Validation Procedure:**
1. Run health check: `psql -U postgres -d cia_dev -f schema-health-check.sql`
2. Validate view documentation: `./validate-view-documentation.sh`
3. Review findings and update documentation
4. Re-run validation to confirm fixes

**Historical Validations:**
- 2025-11-25: Full validation, 100% coverage achieved
- 2025-11-20: Initial validation, identified 11 undocumented views
