tsk8: Implements REST endpoint for recent stories
Added a new REST endpoint to allow clients to get the most recent 
microstories. The endpoint `/api/microstories/recents` returns the six
latest stories.
Also updated the web configuration (web.xml) to make this endpoint 
available, replacing annotation-based setup with XML configuration.
Removed the old `ApplicationConfig` class and moved REST resources from
the `api` package to the new `rest` package for better structure and
consistency.
