Pull Request Overview

This PR fixes date formatting for Date of Birth (DoB) values by simplifying the formatCompactDate function and standardizing date formats across the codebase. The changes ensure consistent handling of date strings in ISO format (YYYY-MM-DD) rather than compact format (YYYYMMDD).

• Simplified formatCompactDate function to use native Date constructor instead of manual string parsing
• Updated mock data to use ISO date format (YYYY-MM-DD) for consistency
• Updated test cases to reflect the new expected input format

• The test coverage for formatCompactDate is insufficient. Consider adding tests for edge cases such as invalid date strings, empty strings, and malformed date formats to ensure the function handles them gracefully.

describe("formatCompactDate", () => {
  it("should format the date as 26 February 1993", () => {
    const input = "1993-02-26";
    const expectedOutput = "26 February 1993";
    expect(formatCompactDate(input)).toBe(expectedOutput);
  });
});
