Reopening a nest regenerated its cut-offs with built-in defaults (no
overtravel, a different minimum segment) rather than the machine's
settings it was made with, so a nest saved, reopened and posted could
cut scrap that never separates. Plates now record the settings their
cut-offs were last generated with, and files carry them; older files
still load with the defaults.
Saving over a nest file truncated it before writing, so any failure
part way lost the only good copy, and the error reached the user as an
unhandled exception after the save path had already changed. Nest and
settings files are now written beside the target and swapped in, and a
failed save is reported with the old file left intact.

Roslyn Bridge flagged these as copy-paste clusters; each pair now shares
one implementation so a fix lands everywhere at once:
- Shape.OffsetInward/OffsetOutward differed only in the target winding.
- BestFitFinder kept its own copy of SpatialQuery's arc-extreme points.
- SplitDrawingForm rebuilt DrawingSplitter's clip-region grid for preview.
- GeometryOptimizer's collinear/coradial finders (one misspelled
GetCoradialArs) become one generic FindRelated.
- Five settings files repeated the write-with-retry loop, and two also
repeated the unit parser and unreadable-file filter (SettingsFile).
- ClampsForm and SupportGridForm repeated their row/box builders.
- Vertical/HorizontalRemnantComparer share a RemnantComparer base.
Behavior is unchanged except that Engine/NestStorage settings loads now
also tolerate NotSupported/Security exceptions, matching the other
settings files' never-throw contract.
