test: Refactor integrity_test.go to use shared DB pattern (bd-1rh P2)

CHANGES:
- Reduced from 15 DB setups to 4 shared DBs
- TestValidatePreExportSuite: 1 shared DB, 5 subtests
- TestValidatePostImport: No DB needed, kept as-is
- TestCountDBIssuesSuite: 1 shared DB, 1 subtest
- TestHasJSONLChangedSuite: 1 shared DB, 7 subtests (with unique keySuffixes)
- TestComputeJSONLHash: No DB needed, kept as-is
- TestCheckOrphanedDepsSuite: 1 shared DB, 2 subtests

PERFORMANCE:
- Before: 0.455s avg (15 DB setups)
- After: 0.373s avg (4 DB setups)
- Speedup: 1.22x (18% faster)

KEY LEARNINGS:
- Used unique keySuffix values for hasJSONLChanged subtests to avoid metadata pollution
- Metadata keys like last_import_hash are shared across subtests unless keySuffix is used
- TestValidatePostImport and TestComputeJSONLHash do not need DB at all

PATTERN:
Following create_test.go and dep_test.go pattern with shared DB setup

Part of Phase 2 test suite optimization (bd-1rh follow-up)
