v15.64.6

## Bug Fixes
* Adds checks when showing or saving employee information, leave requests, holiday lists, expense approvals, activity timelines, and file uploads. **Salary Slip** creation and preview also follow the same access rules. (https://github.com/frappe/hrms/pull/4622)
* Adds checks before listing unmarked days or recording **Attendance**, expiring **Leave Ledger Entry** allocations, and changing **Shift Assignment** records, so invalid employee, leave, or shift details are not processed. (https://github.com/frappe/hrms/pull/5450)
* Keeps the latest attendance record available while the mobile app refreshes, so an employee’s first check-out attempt is less likely to be recorded as a check-in. (https://github.com/frappe/hrms/pull/5458)
* Prevents **Goal** records from being saved when _End Date_ is earlier than _Start Date_. (https://github.com/frappe/hrms/pull/5460)
