feat(hosted): Add error logs if HTTP fails

[me-no-dev]

This pull request introduces improved error reporting for the OTA update process in ESP_HostedOTA.cpp. The code now provides more specific feedback when the update file is not found or when other HTTP errors occur.

Error handling improvements:

• Added a check for HTTP_CODE_NOT_FOUND and a corresponding error message when the update file is missing.
• Added a generic error message for other HTTP error codes, including the code in the output for easier debugging.
