This ticket originates from WT-12861, where we enabled a set of tests for reconfiguration that were previously only checked during the cache creation process. In that ticket, we adjusted the values of eviction_dirty_target and eviction_dirty_trigger in the list of possible configurations to ensure that any randomly selected configuration would pass the check eviction_dirty_target < eviction_dirty_trigger.

Currently, the values of eviction_dirty_target are set to be less than all the values in the list and the default value of eviction_dirty_trigger. While this setup ensures the check passes, it does not provide meaningful test values.

Therefore, the goal of this ticket is to introduce more meaningful test values for eviction_dirty_target and eviction_dirty_trigger, while still ensuring they pass the eviction_dirty_target < eviction_dirty_trigger check.
