v15.52.2

## What's Changed
* Removes the _Type_ filter when choosing a _Salary Component_ in **Additional Salary**, so the correct components show up even after the entry is cancelled and amended. (https://github.com/frappe/hrms/pull/3694)
* Skips the opening balances check in **Salary Structure Assignment** when _Salary Structure_ is not chosen, preventing the error that previously appeared on the form. (https://github.com/frappe/hrms/pull/3695)
* Fixes incorrect date comparisons that blocked the scheduled creation of monthly Earned Leave entries, so employees now receive their allocated leaves on the expected day. (https://github.com/frappe/hrms/pull/3704)
* The "Salary Register" report now counts loan repayments in _Total Deduction_. It also corrects the column headers so _Loan Repayment_ and _Total Deduction_ amounts appear under the right labels. (https://github.com/frappe/hrms/pull/3697)
