Refactor ChannelDetail and MediaImportDialog components for improved functionality and clarity

Consolidated imports in ChannelDetail and replaced the SchedulePreview component with AirSchedule for enhanced scheduling display. Updated the MediaImportDialog to prioritize the manual tab and adjusted localization strings for clarity in both English and Russian. These changes aim to streamline user interactions and improve the overall user experience in managing channels and media imports.
