  SAXS extrap-to-c0 regplot: real window, smooth wheel, merge-aware labels

Fixes reported in first testing of the per-q regression pop-up:

- It rendered inside the SAS window instead of as its own window. It is a
  QFrame parented to the SAS window, which without a window flag is an
  embedded child. Set Qt::Window so it is a proper top-level window.

- The wheel snapped one step at a time (useless for scrolling) because the
  wheel-driven handler called set_index(), which reset the wheel value back
  to the integer index. Now dragging the wheel updates the plot to the
  nearest q WITHOUT snapping, so it scrolls smoothly; only Prev/Next snap
  the wheel and step by one q. Wheel given continuous fine steps, inertia
  (setMass(1.0)) so a flick keeps scrolling, and a minimum width.

- Primus mode is a weighted merge (slope 0), so "intercept at c=0" no longer
  fits. Added a merge_mode flag: the pop-up now labels the result "merged
  value", drops the c=0 vertical reference line, and drops the slope readout
  in Primus; Zimm is unchanged. Manual updated.
