v16.15.0

## Features
* Adds a **Contract** section to the **Employee** form so users can see and create contracts linked to that employee. (https://github.com/frappe/hrms/pull/4986)

## Bug Fixes
* Fixes **Salary Slip** naming for Data Import so imported slips use the correct _Employee_ in their name. (https://github.com/frappe/hrms/pull/4983)
* The **Interview** form now displays a failure message instead of an error when updating the status of a **Job Applicant** record that is missing or invalid. (https://github.com/frappe/hrms/pull/5003)
* In the "Employee Leave Balance" report, the _Employee_ filter now shows only employees belonging to the selected _Company_. Changing _Company_ clears the _Employee_ filter. (https://github.com/frappe/hrms/pull/5007)
* Formats the dates in _Earned Leave Schedule_ on **Leave Allocation** using the date format set in **System Settings**. The red and green status markers still appear next to each date. (https://github.com/frappe/hrms/pull/5008)
