fix: S/M/L font size buttons now take effect immediately

saveSetting() for DEVICE_SETTINGS_KEYS (viewDays, cellDuration, startHour,
endHour, fontSize, showSubHourSlots) was saving to the cookie but returning
early before calling setProfile — so profile.fontSize never changed and the
CSS class font-size-s/m/l was never applied. Adding setProfile() to the
device-settings path fixes all of these keys at once while still keeping
the setting out of the DB.
