Add Arve integration (#113156)

* add Arve integration

* Update homeassistant/components/arve/config_flow.py

Co-authored-by: Josef Zweck <24647999+zweckj@users.noreply.github.com>

* Various fixes, changed scan interval to one minute

* coordinator implementation

* Code cleanup

* Moved device info to the entity.py, ArveDeviceEntityDescription to sensor.py

* delete refresh before adding entities

Co-authored-by: Josef Zweck <24647999+zweckj@users.noreply.github.com>

* Update tests/components/arve/test_config_flow.py

Co-authored-by: Josef Zweck <24647999+zweckj@users.noreply.github.com>

* Update tests/components/arve/conftest.py

Co-authored-by: Josef Zweck <24647999+zweckj@users.noreply.github.com>

* Changed value_fn in sensors.py, added typing to description

* Code cleanups, platfrom test implementation

* New code cleanups, first two working tests

* Created platform test, generated snapshots

* Reworked integration to get all of the customer devices

* new fixes

* Added customer id, small cleanups

* Logic of setting unique_id to the config flow

* Added test of abortion on duplicate config_flow id

* Added "available" and "device" properties fro ArveDeviceEntity

* small _attr_unique_id fix

* Added new test, improved mocking, various fixes

* Various cleanups and fixes

* microfix

* Update homeassistant/components/arve/strings.json

* ruff fix
