v16.13.0

## 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/4897)

## 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/4874)
* 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/4875)
* The _Total Expense Claim (via Expense Claims)_ field in **Project** now includes amounts from expense line items assigned to the project, whether the project is set on the main **Expense Claim** or on a line item. (https://github.com/frappe/hrms/pull/4877)
* 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/4868)
* Removes an unused request for currency precision from **System Settings** when the app loads. This helps avoid a permission error for employees who do not have access to that setting. (https://github.com/frappe/hrms/pull/4900)
* Skips loading dashboard details and feedback on new **Job Applicant** and **Interview** forms until they are saved, so blank forms no longer show an error popup. Saved forms continue to show these details as before. (https://github.com/frappe/hrms/pull/4902)
* Adds the configured connection port to the app startup data so the PWA uses the site’s port instead of always falling back to 9000. (https://github.com/frappe/hrms/pull/4901)
* Adds default values for missing **Salary Slip** fields and _Unmarked Days_ in **Salary Structure Assignment**, so payroll calculations can still use those values when they are blank. (https://github.com/frappe/hrms/pull/4906)
