🛡️ Sentinel: [CRITICAL] Fix SQL injection in jsonExtract parameterization

[Donach]

🚨 Severity: CRITICAL
💡 Vulnerability: The jsonExtract helper in database-wrapper.ts used sql.raw to interpolate JSON paths. This bypasses Drizzle's parameterization, exposing the database to SQL injection if dynamic, unvalidated keys are passed as paths.
🎯 Impact: An attacker could supply malicious strings to a JSON path resulting in SQL syntax manipulation and potential extraction or modification of sensitive database content.
🔧 Fix: Replaced sql.raw manual interpolation with parameterized queries using sql\->> (${key}::text)`andsql.jointo safely concatenate paths. The::textcast solves parameterization typing issues while maintaining safety. ✅ Verification: Runpnpm -w run lint:fixandpnpm --filter @agor/core test` to ensure tests pass and verify the query executes securely.
