v15.63.0

## Features
* Adds "Single Assignment" and "Bulk Assignment" buttons to the **Leave Policy** form once it is submitted. "Single Assignment" opens a new **Leave Policy Assignment**, and "Bulk Assignment" opens **Leave Control Panel** with the _Leave Policy_ field already filled in. (https://github.com/frappe/hrms/pull/4896)

## Bug Fixes
* In the PWA, dropdown fields now keep a value selected from search results even when it is not in the initial list. The list also reloads when the value is cleared or changed from elsewhere. (https://github.com/frappe/hrms/pull/4873)
* Blocks a half-day **Leave Application** when a full-day leave already exists for the same date. (https://github.com/frappe/hrms/pull/4843)
* Shows a confirmation warning when you close a **Job Opening** linked to a **Staffing Plan**. You can still close it even when the plan is already full, and reopening a closed **Job Opening** still follows the same checks as before. (https://github.com/frappe/hrms/pull/4867)
* Shows the employee ID on the profile page when _Employee Number_ is not set. Displays the manager’s name in _Reports To_ instead of leaving the field blank. (https://github.com/frappe/hrms/pull/4870)
