feat(devops): Add automated CI safety checks and documentation validation

[heymariam]

DESCRIPTION:

🎯 Overview

This PR implements three critical CI automation features to enhance code quality, security, and API documentation accuracy. These features work together to catch issues early in the development pipeline before code reaches production.

📋 Issues Resolved

Closes #124
Closes #125
Closes #126
Closes #127

✨ What's New

124. Add automated Docker build & multi-stage container optimization workflow

125. Database Migration Safety Check (scripts/test-migrations.sh)

• Validates all TypeORM migrations execute successfully in forward direction
• Tests rollback capability to ensure migrations can be safely reverted
• Verifies idempotency by re-applying migrations
• Integrated into CI pipeline to run after dependencies install
• Provides colored output and descriptive error messages
• Exit codes: 0 (success), 1 (forward migration failed), 2 (rollback failed), 3 (re-application failed)

126. Dependency Vulnerability Scanning (.github/workflows/security-scan.yml)

• Automated Trivy filesystem scanner detecting CRITICAL and HIGH severity vulnerabilities
• Additional npm audit validation for production dependencies
• SARIF format integration with GitHub Security Dashboard
• Runs independently on every PR and push to dev/develop branches
• Security summary report in GitHub Actions workflow tab
• Prevents merge of PRs with critical vulnerabilities

127. OpenAPI Schema Drift Checker (scripts/verify-openapi-sync.ts)

• Validates all Express routes are documented in OpenAPI spec
• Extracts registered routes from app.ts and compares with docs/openapi.json
• Detects missing or undocumented endpoints
• Integrated as npm run verify:openapi script
• Runs early in CI to catch documentation drift before expensive tests
• Exit codes: 0 (all documented), 1 (routes missing), 2 (spec invalid)

🔧 Technical Changes

Files Modified:

• .github/workflows/api-cy.yml - Added OpenAPI drift check and reordered CI steps
• package.json - Added verify:openapi npm script

Files Created:

• .github/workflows/security-scan.yml - Trivy security scanning workflow
• scripts/test-migrations.sh - Migration validation script (bash)
• scripts/verify-openapi-sync.ts - OpenAPI drift checker (TypeScript)

✅ Verification

• All 299 existing tests pass
• TypeScript compilation successful
• ESLint linting passes
• Production build successful
• New scripts tested and working correctly
• CI workflow YAML syntax valid

🚀 CI Pipeline Impact

The three new checks run in this order:

1. OpenAPI Schema Drift Check - Fast, catches documentation issues early
2. Database Migration Safety Check - Validates schema integrity
3. Dependency Vulnerability Scan - Runs in parallel (separate workflow)
4. Linting, type-checking, testing, and build (existing steps)

📝 Notes

• Migration safety check runs against PostgreSQL 14 test database
• Security scan targets dev and develop branches
• OpenAPI validator gracefully handles internal endpoints (/health, /metrics, /health/db)
• All scripts follow project conventions and TypeScript standards
• No breaking changes to existing functionality
