tsk8: Implements REST tests for recent stories
This commit introduces REST integration tests for the
`/api/microstories/recents` endpoint, verifying that the service
correctly retrieves and orders the 6 most recent stories. To ensure
consistent results, the timestamp handling in `StoriesDataset` and the
XML datasets was adjusted to align with DBUnit expectations. The dataset
files now use SQL-style timestamps (`yyyy-MM-dd HH:mm:ss`), and
`StoriesDataset` uses
`LocalDateTime` instead of `Instant.parse()` to avoid timezone
discrepancies. These changes guarantee that the test data and database
values are interpreted consistently across environments.

tsk8: Fixes missing dataset location and adds cleanup scripts for REST
tests
This commit fixes a dataset resolution error in the REST integration
tests for the
/api/microstories/recents endpoint. The Arquillian persistence extension
was unable to locate stories.xml, so the dataset file was moved to the
datasets/ directory, matching the framework’s default lookup path.
Additionally, a cleanup.sql script was introduced to clear test tables
between executions, ensuring isolation and preventing residual data
issues.

tsk32: Fix date format for testing
Date format fixed to pass tests due to time offset
