ref: Rename package ch.parano.myice to ch.parano.myicek

Complete the MyIceK rename by updating the Kotlin package from ch.parano.myice to ch.parano.myicek across all source sets (androidMain, commonMain, desktopMain, iosMain, commonTest), the build.gradle.kts (namespace, applicationId, mainClass, desktop packageName) and the iOS Info.plist bundle URL name. The myice:// OAuth scheme is kept unchanged as it depends on the backend.

Also add pull-to-refresh to ScheduleScreen using Material 3 PullToRefreshBox, replacing the manual loading overlay.
