🛡️ Sentinel: [HIGH] Fix sensitive schema details leakage in public share exports

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: Publicly shared schema snapshot export routes (SQL, DB Reversing Spec, Index Design Spec) returned the entire JSON payload without redacting sensitive fields.
🎯 Impact: This could expose sensitive internal schema comments (comment, relation_comment, column_comment) or sensitive data in example_value fields to users with access to public share links.
🔧 Fix: Updated the export endpoints in backend/app/api/share.py to recursively redact the snapshot_json payload using the existing _redact_sensitive_snapshot_fields utility before generating the exports.
✅ Verification: Ran all backend (pytest) and frontend (pnpm test) suites. All 560 tests successfully pass without regressions.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head b4c31538293aca364784ab2031ea91fa4e2b3ac5.
