Remove the dedicated Carrier Type accordion step and merge the
Image/Audio toggle into the Carrier & Mode step. The toggle now sits
in a two-column row aligned with the embedding mode buttons. Steps
renumbered from 4 to 3, carrier label changed to "Carrier File",
mode hint updates on carrier type switch via dispatched change events.

DCT steganography improvements:
- Add _apply_exif_orientation() to fix portrait photos encoding rotated
- Add _jpegtran_rotate() for lossless JPEG rotation preserving DCT data
- Add rotation fallback in extract_from_dct() - tries 0°, 90°, 180°, 270°
- Quick header validation to skip invalid rotations efficiently
- Fix: wrap debug.print in try/except to prevent extraction failures
Web UI rotate tool:
- Use jpegtran for JPEGs (lossless, preserves DCT steganography)
- Fall back to PIL for non-JPEGs
- Dynamic UI shows "DCT Safe" for JPEGs, warning for other formats
This enables the workflow: encode → compress → rotate → decode
Rotated stego JPEGs can now be decoded by trying all orientations.

Removed gold outline/stroke from default state - too harsh on
some monitors. Now simple white icons that turn gold on hover
like the header nav, with lift effect and drop shadow.
