[CAL-3580] [Api][v2] schedules endpoints should be client agnostic

[ThyMinimalDev]

• createSchedule
• getDefaultSchedule
• getSchedule
• getSchedules
• updateSchedule
  • updateScheduleHandler from platform-libraries seems to already format data for client, do another prisma call inside of v2 to get the data instead of returning directly data from this handler
• deleteSchedule

remove all mentions of Atoms, function formatScheduleForAtom should be used inside of atoms PlatformWrappers

• useClientSchedule
• useDeleteSchedule
• useUpdateSchedule
• add a new hook useCreateSchedule
• add a new hook useGetSchedules
