Add tests for payouts route filter, sort, and pagination allowlists

[thlpkee20-wq]

Description

src/routes/payouts.ts enforces allowlists for status, sortBy, sortOrder, and a MAX_LIMIT of 100, but these guards need tests proving invalid values are rejected with 400 and that pagination cannot be abused for large result sets. Expand src/routes/payouts.test.ts to cover the validation surface.

Requirements and context

• Must be secure, tested, and documented
• Should be efficient and easy to review
• Relevant code: src/routes/payouts.ts, src/routes/payouts.test.ts
• Out-of-allowlist sortBy must never reach a SQL query (injection prevention)

Suggested execution

• Fork the repo and create a branch
• git checkout -b test/payouts-filter-pagination
• Implement changes
  • Add tests for invalid status, sortBy, sortOrder returning 400
  • Assert limit above MAX_LIMIT is clamped or rejected
  • Assert default limit of 20 applied when omitted
• Validate security and correctness assumptions

Test and commit

• Run tests
  • npm test
• Cover edge cases
  • limit=0, negative offset, sortBy=created_at;DROP, non-numeric limit
• Include test output and notes

Example commit message

test: cover payouts filter and pagination guards

Guidelines

• Minimum 95 percent test coverage
• Clear documentation
• Timeframe: 96 hours
