feat(QsTile/Dimmer): continue cycle from current strength level

[FineFindus]

Continues the cycle from the current strength level by mapping the current level to the next cycle level. For example, if the user has already activated the torch from another application and has set it to 2 (out of 10), the tile will show the minimum state.
