fix: apply EXIF orientation to service record images in PDF/DOCX

Smartphone photos often have EXIF orientation metadata (tags 6, 8, 3)
that rotates the display but doesn't transform the pixel data. When
PDFs/DOCX embedded images without applying this metadata, they appear
rotated 90/180/270 degrees.

Use ImageOps.exif_transpose(img) before resize/convert in both
_compress_image_for_pdf() and _compress_image_for_docx() to read EXIF
orientation and transpose the actual pixel data accordingly. This is
a standard Pillow function and is a no-op for images without EXIF.

Add regression test test_compress_image_for_docx_handles_exif_orientation
to verify images with EXIF tag 0x0112 (orientation=6) are transposed.
