v15.56.0

## What's Changed
* Employees can now open the Organizational Chart page, thanks to the added Employee role in its access permissions. (https://github.com/frappe/hrms/pull/3995)
* Fixes the error that occurred when opening the report view from the **Employee Separation** list by filtering on _Boarding Status_ instead of _Status_. Users can now switch between these views without the query error message. (https://github.com/frappe/hrms/pull/4005)
* **Salary Slip** now ignores disabled tax components, so only active taxes appear in the breakdown and totals. (https://github.com/frappe/hrms/pull/4009)
* **Expense Claim** now adds taxes and charges to the _Allocated Amount_ when applying employee advances, reducing unallocated balances and displaying accurate claim totals. (https://github.com/frappe/hrms/pull/4015)
* Adds permission checks when fetching data from **Employee** records, preventing Desk and Website users without the right permissions from viewing confidential employee fields. (https://github.com/frappe/hrms/pull/4011)
