test(06-01): create test infrastructure for Lab 05 Database & RDS

Test Scripts (7 files, 1000+ lines):
- 01-database-creation-test.sh: PostgreSQL creation and initialization
- 02-private-network-test.sh: Private network isolation (INF-02)
- 03-persistence-test.sh: Data persistence verification (INF-04)
- 04-security-test.sh: Security compliance (INF-01, INF-02, INF-03)
- 99-final-verification.sh: End-to-end student verification
- run-all-tests.sh: Test orchestration with fail-fast
- quick-test.sh: Quick validation (< 30s)

Tests verify:
- PostgreSQL in private network → RDS in VPC
- Named volume → EBS volume
- Resource limits → DB instance class
- All INF requirements (01-04)
