Normalize DB query results and fix admin claims for Neon direct-array responses

[GsCommand]

Motivation

• The admin claims endpoints were failing with 500 errors when using @neondatabase/serverless because Neon can return a direct-array result shape instead of the { rows } shape returned by pg clients.
• Normalize database result shapes so route handlers can safely consume rows regardless of driver shape and avoid runtime crashes.
• Add tests covering both pg-style { rows: [...] } and Neon direct-array responses to prevent regressions and enable safe non-production debug data.

Description

• Added normalizeQueryResult() and normalizeRows() to lib/db.js and made query() always return a { rows } shape by normalizing Neon direct-array results.
• Updated api/admin/claims.js to use db.normalizeRows(result) for mapping claims and to include a safe debug object only when NODE_ENV !== 'production'.
• Updated api/admin/claim.js to normalize claim/agent/event query results with db.normalizeRows(...) and to include the same safe non-production debug payload on failure.
• Expanded tests/api-admin-claims.test.js to mock both pg-style and Neon direct-array query responses for list and detail endpoints and updated the test DB loader to provide normalizeRows during tests.

Testing

• Ran npm test and all tests passed (69 tests passed, 0 failed).
• Ran cd examples/webhook-auto-verify && npm run check and the example checks completed successfully.
• Added unit tests in tests/api-admin-claims.test.js that exercise both { rows: [...] } and direct-array results and they succeeded under the test runs.
