fix: replaced Date with java.time API (#397)

[petruki]

This pull request modernizes date and time handling throughout the codebase by replacing legacy Date and DateUtils usage with Java 8+ time APIs (Instant, LocalDateTime, DateTimeFormatter, etc.). The changes improve code readability, reliability, and future-proof the code by leveraging the more robust and thread-safe Java time library. The updates also include corresponding changes in tests and utility methods.

The most important changes are:

Migration to Java Time API:

• Replaced all uses of Date, SimpleDateFormat, and DateUtils with Instant, LocalDateTime, and DateTimeFormatter in both production code and tests for date and time manipulation and parsing. [1] [2] [3] [4] [5] [6]

Core Utility and Service Updates:

• Refactored SwitcherUtils.addTimeDuration to use Instant and ChronoUnit instead of Date and DateUtils, and updated all its usages accordingly. [1] [2] [3]

Validator Refactoring:

• Updated DateValidator and TimeValidator to use LocalDateTime and DateTimeFormatter, including parsing, comparisons, and exception handling. This affects how date and time operations (e.g., LOWER, GREATER, BETWEEN) are implemented. [1] [2]

Test Suite Adjustments:

• Refactored all affected tests to use the new Java time APIs, including updating test data setup, assertions, and helper methods in SwitcherUtilsTest and MockWebServerHelper. [1] [2] [3]

Dependency Cleanup:

• Removed unnecessary imports for DateUtils, SimpleDateFormat, and related legacy date/time classes from all affected files. [1] [2] [3] [4] [5] [6] [7]
