This update simplifies employee payroll management by introducing a 'Simulation' button on the employee form. Clicking this button launches a salary calculator pre-populated with employee data, allowing users to quickly assess potential costs. The monthly cost field has been removed and replaced with an 'Employer Cost' field for clarity and accuracy.

Improve the UX of the Employee Payroll Tab by removing `Monthly Cost` and changing the position of Yearly Cost and renaming it to Employer Cost. 
Add a `Simulation` button in the employee form view; by clicking it, it leads to the salary calculator view with already loaded data from the employee.
