Description
Is your feature request related to a problem? Please describe.
The current editor in the viewer app only manipulates the whole image. If saved as JPEG or WEBP, it is a lossy process.
It would be excellent to add the rotation and flip functionality that is already implemented in the Memories app, that only manipulates the orientation in the metadata, and so is lossless.
Since this is a very common operation if you manage your photos in Nextcloud, it should be fast and easy to use, and should not change the image itself, only its metadata.
Describe the solution you'd like
Add the tools from the Memories app to flip and rotate images by manipulating the EXIF tag.
See https://github.com/pulsejet/memories/blob/master/src/components/modal/EditOrientation.vue.

Research direction
Start by reading Memories' src/components/modal/EditOrientation.vue and then locate the corresponding editor entry point in the viewer app. Compare the existing viewer editing flow with the referenced orientation tools. Done means users can rotate and flip supported images by changing only the EXIF orientation metadata, without rewriting image pixels.
