Session restore fixes:
- AUTO-typed folders now default to MAIN on restore instead of using
position-based index%2, which silently flipped half the folders to
TRANSITION when restoring legacy sessions
- All restored folders get explicit type overrides so no folder relies
on position-based typing after restore
- TRANSITION folders with symlink data are auto-recovered as MAIN
(catches incorrectly saved types from older export paths)
- Export Sequence path now saves with save_effective_types=True,
preventing folder type loss
- Removed redundant trim-only save that used unresolved paths
- Auto-save guards against overwriting sessions with empty file lists
UI improvements:
- Added 4th "Frame" column to Sequence Order tab showing overall
frame number (1-based)
- Last frame of each sequence is bold for visual clarity
- Fixed column resizing (ResizeToContents + Stretch) to prevent
column collapse bugs
- Save Session dialog now reports main + transition folder counts
- Default optical flow preset changed to Max
