Description
ImageMagickHandler::save() unconditionally called $this->resource->setImageFormat($extension) outside of error handling, throwing an uncaught ImagickException when saving without an extension or with an unsupported extension (e.g., .tmp). This change checks against Imagick::queryFormats(), falls back to the current image type format, and wraps the operation in standard image save failure handling.

pls use strict boolean check for $format

Imagick::queryFormats() can be assigned to a local variable then reused.

Could you also update the note under Converting Images? With this change, the ImageMagick handler uses $imageType as a fallback when the target has no extension or an unsupported extension:

When using ImageMagick, a supported target filename extension determines the output format and takes precedence over $imageType. If the target has no extension or an unsupported extension, the handler uses $imageType instead.

Please also update the existing note about save() under Image Quality to mention this fallback, while preserving the guidance about format prefixes and input validation.
