sar3d: python plumbing for the new parameters and real replay timing

- replay_raw_producer carries the RECORDED per-trace capture windows
  from each snapshot's meta.json (re-anchored by the same shift as the
  frame time) instead of one synthetic window for all traces — without
  this the segmented timing model degenerates in replay;
- GUI/profile/orchestration swap the removed window knobs
  (center_depth, half_width_*, grid_n*) for the notebook parameters
  (ground depth, pitch override, voxel pitch, Y range, X margin, norm
  edge margin, smooth sigma, comp power, tx per segment).

Headless replay smoke on the 20260922_mine_fast_true dataset passes:
51 sar3d result collections, transparent preprocessor.
