Move BuildRotatedPattern and FillPattern static methods into a new
public FillHelpers class in Strategies/. DefaultNestEngine retains
internal static forwarding stubs so existing callsites are unchanged.

- FillExtents.Fill reported progress internally which overwrote the UI's
temporary parts even when a better result (e.g. Pairs with 70 parts)
won the competition. Added final ReportProgress call in FindBestFill
and Fill(groupParts) to ensure the UI always shows the actual winner.
- FillExtents vertical copy distance clamp (Math.Max with pairHeight +
spacing) prevented geometry-aware compaction from ever occurring,
causing visible gaps between rows. Boundaries are already inflated by
halfSpacing so the calculated distance is correct; only fall back to
bounding-box distance on non-positive results.
- PairFiller now sets RemainderPatterns on FillLinear so remainder strips
get pair-based filling instead of only individual parts (+1 part in
tight layouts).

Adds FillExtents as a fourth nesting phase in both FindBestFill and
Fill(groupParts, Box), running at bestRotation and bestRotation+90°.
Updates Description to reflect the new phase.

The Size fix (d4222db) changed Size.Width to Y axis and Size.Length to
X axis but only updated DrawPlate/LayoutViewGL. BoundingBox, WorkArea,
rotations, DXF export, and engine code still used the old Width=X
convention, causing the fill engine to get a swapped work area (60x120
instead of 120x60) and parts to fill in the wrong direction.
