* Add files via upload

Add device config for Smart Light RGB48 RGBIC string lights

* Update smart light rgb48.yml

Address review feedback: fix DP types, separate timer entity, add LED count and scene entities

* Update smart light rgb48.yml

* Update smart light rgb48.yml

Removed DP 24 from light entity entirely as it was causing a TypeError in tuya-local’s light.py due to missing format names

* Update smart light rgb48.yml

Fixed for linting - added new line at end of file.

* fix (rgb48_lightstring): file naming, translations and others

- rename file to follow general naming scheme
- use translation keys for scene and timer
- use time entity for timer
- hide the unavailable options for the light

PR #4735

* fix (rgb48_lightstring): use consistent yaml extension

- tests were skipped due to wrong extension used.
