/**
 * Compare two ISO date-like strings for equality, ignoring time components.
 *
 * - Accepts both PlainDate and PlainDateTime strings.

 * - Returns false if either input is invalid.
 *
 * @param value1 ISO date-like string
 * @param value2 ISO date-like string
 * @returns true if the dates are equal, false otherwise
 *
 * @example areDatesEqual("2024-02-29", "2024-02-29T12:34:56") // true
 * @example areDatesEqual("2024-02-29", "2024-03-01") // false
 * @example areDatesEqual("invalid", "2024-02-29") // false
 * @example areDatesEqual("2024-02-29", "invalid") // false
