fix(test): use dynamic dates in AdminRoleAccessControlTest

Replace hardcoded date strings with dynamically generated future dates
to prevent test failures when dates pass.

The tests were using hardcoded date "2025-12-31" which failed validation
against @FutureOrPresent constraint after that date passed. Added a
futureDate() helper method that returns LocalDate.now().plusYears(1)
to ensure dates are always valid.
