SafeAppointment type actually doesn't have this properties, so I have removed them

[Copilot]

Pull request overview

This PR introduces a new internal Scheduler appointments rendering implementation (behind the _newAppointments option), including incremental rendering via view model diffing, plus supporting utilities, styling updates, and test coverage.

Changes:

• Added appointments_new components (appointments container, base appointment, grid/agenda appointments, collector) and utilities (diffing, targeted appointment, date text) with Jest tests.
• Integrated the new appointments implementation into m_scheduler.ts when _newAppointments is enabled.
• Updated Scheduler appointment CSS selectors and refreshed TestCafe visual etalons accordingly.
