Closes #193

[Kimoo193]

This pull request introduces a new feature for handling sprint deletion in the project management system. It includes the addition of a deleteSprint controller method for soft-deleting sprints and updates to the routing to support the new functionality.

New sprint deletion functionality:

• Added deleteSprint controller method: Implements a soft delete for sprints, including validation of parameters, permission checks, prevention of deletion for active sprints with unfinished tasks, and audit logging. The deletion process uses a transaction to ensure data consistency. (src/controllers/sprint.controller.js, src/controllers/sprint.controller.jsR957-R1096)

Routing updates:

• Added DELETE route for sprint deletion: Configured a new route to handle DELETE requests for sprints, integrating the deleteSprint controller and verifyAccessToken middleware. (src/routes/sprint.routes.js, src/routes/sprint.routes.jsR43-R47)
