Kulersky refactor to new Bluetooth subsystem

[emlove]

Proposed change

👋🏻 It's been a while!

This PR updates the kulersky component to use the core Bluetooth system instead of setting up its own Bleak scanner. This means that these devices can now be automatically discovered!

Upstream changelog: https://github.com/emlove/pykulersky?tab=readme-ov-file#changelog

The biggest upstream change is that it now allows a BLEDevice to be passed down to the underlying BleakClient so that it can take advantage of the BLEDevice from the hass bluetooth component.

Hi! Welcome back 🎉

Looks like the link to the changelog is pointing at the wrong location.
