Pull request overview

This PR reverts the Remote platform that was recently added to the SMLIGHT integration. The Remote platform was added as part of a feature to support infrared capabilities on SLZB-Ultima devices, but the implementation is being rolled back to be reimplemented as an Infrared platform instead. Since this feature only exists on the dev branch and hasn't been released to users, the revert is safe.

Changes:

• Removed the Remote platform implementation file (remote.py)
• Removed Remote platform from the PLATFORMS list in __init__.py
• Removed Remote entity strings and the send_ir_code_failed error message from strings.json
• Removed all Remote platform tests
