125 test files had beforeEach/beforeAll but no afterEach/afterAll,
leaking state between tests and causing order-dependent failures.
Added cleanup to 104 files (skipped 4 archived, 16 import-only):
- 2 critical DB handle leaks (witness-chain): added db.close()
- 7 high-risk service files: added vi.restoreAllMocks()
- 7 beforeAll files: added matching afterAll
- 88 medium/low risk: added afterEach with appropriate cleanup
