feat(gro-107): add CalendarSync UI component and calendar unit tests

- Add CalendarSync component with generate/revoke/copy functionality
- Add unit tests for generateIcalToken function
- Fix StaffRow type in petPhotos.test.ts and rbac.test.ts to include icalToken

The CalendarSync component can be added to a staff profile/settings page.
Currently the Staff page (admin/staff) does not have a profile section
for individual staff - integration will need a new route or profile section.
