Fix #328: Remove duplicate computeJSONLHash declaration

The function was declared twice:
- Line 80: New version (simpler, no error wrapping)
- Line 390: Old version (with error wrapping)

This caused compilation failure in CI. Removed the old declaration at line 390.

Also fixed integrity_content_test.go to pass context.Context to sqlite.New()
as required by the updated API.
