Subject: [PATCH 2/2] fix: apply EXIF orientation during thumbnail generation
 with sharp .rotate()

Add .rotate() before .resize() in all thumbnail generation paths so that
EXIF Orientation metadata is respected. This fixes rotated thumbnails for
smartphone photos in Gallery View and attachment previews.

Closes #2854
