* Add buttons to Blue current integration
* Apply feedback
* Changed configEntry to use the BlueCurrentConfigEntry.
The connector is now accessed via the entry instead of hass.data.
* Changed test_buttons_created test to use the snapshot_platform function.
Also removed the entry.unique_id check in the test_charge_point_buttons function because this is not needed anymore, according to https://github.com/home-assistant/core/pull/114000#discussion_r1627201872
* Applied requested changes.
Changes requested by joostlek.
* Moved has_value from BlueCurrentEntity to class level.
This value was still inside the __init__ function, so the value was not overwritten by the ChargePointButton.
