fix: apply EXIF rotation in crop pipeline and add regression tests

[robinvangestel21]

What?

This PR fixes EXIF-orientation handling in the upload crop pipeline.
Specifically:

• apply sharp().rotate() before .extract(...) in cropImage so crop coordinates are applied in the same oriented coordinate space as other upload transforms
• apply .rotate() in the animated metadata read path used by the no-op crop branch to keep dimension handling consistent
• add regression tests in cropImage.spec.ts for:
  • EXIF-oriented crop behavior

Why?

Cropping images with EXIF orientation > 1 could behave incorrectly because crop extraction was not using the same EXIF-normalized orientation path as the rest of upload processing.
This could lead to:

• wrong crop orientation / flipped output
• in some cases, crop failures (e.g. bad extract area) due to coordinate mismatch
  Related issue: #16347

How?

• Updated packages/payload/src/uploads/cropImage.ts:
  • added .rotate() before metadata read in the animated branch
  • added .rotate() before crop .extract(...)
• Added packages/payload/src/uploads/cropImage.spec.ts with targeted regression coverage
• Verified test run:
  • pnpm vitest packages/payload/src/uploads/cropImage.spec.ts
