v16.18.0

## Features
* Adds a "Create Employee" action for accepted **Job Applicant** records that opens a prefilled **Employee** with the applicant’s _First Name_, _Personal Email_, _Cell Number_, _Designation_, _Salary Currency_, and _Job Applicant_ link, plus _Company_, _Department_, and _Employment Type_ from the linked **Job Opening** when available. If an employee already exists, the action changes to "Show Employee". (https://github.com/frappe/hrms/pull/5172)
* Enables manual data imports through the Data Import Tool for selected HR and Payroll records. (https://github.com/frappe/hrms/pull/5207)
* Adds "Classic", "Detailed", and "Compact" payslip layouts for **Salary Slip**, with options for everyday, full-detail, and email-friendly printing. Displays the same rounded or unrounded net pay in the amount and in words, based on the payroll settings. (https://github.com/frappe/hrms/pull/5211)
* Adds an _Employer Contribution_ section to **Salary Slip** records so employer-paid amounts, such as ESI, appear separately from employee deductions. These amounts remain hidden on printed slips and can be hidden from employees by users with the required permissions. (https://github.com/frappe/hrms/pull/5218)

## Bug Fixes
* Updates the _Employee_ filters in HR and Payroll reports to show employees from the selected _Company_. (https://github.com/frappe/hrms/pull/5198)
* Clears _From Date_ and _To Date_ in **Additional Salary** when _Is Recurring_ is turned off, and clears _Payroll Date_ when it is turned on, so dates from the inactive schedule are not saved or used in duplicate and overlap checks. (https://github.com/frappe/hrms/pull/5196)
* Stops cancelled **Job Offer** records from appearing in **Job Applicant** details when an applicant is loaded. (https://github.com/frappe/hrms/pull/5200)
* Sets _Print Format For_ to `DocType` so bundled **Print Format** records appear in the print format selection list. Assigns the standard **Salary Slip** formats to the Payroll module. (https://github.com/frappe/hrms/pull/5202)
* Fixes PWA check-in and check-out messages that reported success when no **Employee Checkin** record was created; failed requests now show a fallback failure message when no error message is returned. (https://github.com/frappe/hrms/pull/5209)
* Fixes **Payroll Entry** employee selection when user permissions reference linked DocTypes such as **Employee Grade**. The filter now uses the corresponding field on **Employee** instead of treating the linked DocType name as a field. (https://github.com/frappe/hrms/pull/5210)
* Adds translation support for HRMS progressive web app installation instructions and validates search input before processing it. (https://github.com/frappe/hrms/pull/5224)
