fix(gro-48): add missing icalToken to schema and test fixtures

StaffRow now requires icalToken (from iCal calendar feed feature).
Adding icalToken: null to MANAGER mock in groomerIsolation.test.ts,
petPhotos.test.ts, rbac.test.ts, and buildStaff factory. Also adding
icalToken column to staff table schema to match origin/main.
