UI: Move ScalingIndication to dedicated file (#563)

### TL;DR
Moved scaling indication logic into its own file and cleaned up unused imports

### What changed?
- Relocated `ScalingIndication` object from `Klickable.kt` to a dedicated `ScalingIndication.kt` file
- Removed unused imports from `Klickable.kt`
- Renamed `Indication.kt` to `ScalingIndication.kt` to better reflect its contents
