New schema — VA Form 26-8923

Summary

This PR introduces a new JSON Schema for VA Form 26-8923 (Interest Rate Reduction Refinancing Loan Worksheet). The schema covers:

• Loan Identification: Header fields capturing the VA loan number, lender name, loan officer name, and officer title, all of which are required.
• Shared Definitions: Reusable definition references including:
  • dollarAmount — a numeric type constrained between 0 and 9,999,999.99 for monetary fields.
  • percentageThreeDecimal — a numeric type constrained between 0 and 99.999 for interest rate and fee percentage fields.
  • isoDate — an ISO 8601 date string validated via both format: date and a ^\d{4}-\d{2}-\d{2}$ regex pattern.
• additionalProperties: false is enforced at the root and on nested objects to prevent unrecognized fields.
• Required field arrays are defined at the object level for strict validation of critical identifying information.

Notes for reviewer

• Please ensure you have incremented the version in package.json
• Please add backend-review-group as a reviewer
• The dollarAmount definition uses a maximum of 9999999.99 — please confirm this ceiling is appropriate for all monetary fields in the form (e.g., loan amounts, funding fees).
• The percentageThreeDecimal definition supports up to three decimal places (e.g., 4.375) — verify this aligns with how interest rates are captured on the physical form.
• vaLoanNumber is typed as a string — confirm whether any format constraint or length validation is expected for this field.
• The isoDate definition uses both format and pattern for date validation; downstream consumers should be aware that format enforcement varies by validator implementation.
