The fit panel replaces the three-point wizard

Calibration is now a direct-manipulation overlay: the robot's rooms as
a dashed translucent ghost over the plan, dragged into place and
stretched by four corner handles (uniform scale about the opposite
corner). Quarter-turn and mirror buttons re-anchor about the ghost
centre; mirror defaults on because every robot map seen so far flips Y
versus the screen — measured on the owner's X50. Everything folds into
the same stored 6-number matrix, and legacy matrices reopen in the
panel with rotation snapped to a quarter. The park-the-robot-three-
times wizard is deleted outright: it was the most fragile part of the
feature (owner: «плохо работает»). fitMatrix/fitFromMatrix/initialFit/
reanchorFit are pure and unit-tested; the smoke drives the panel end to
end — drag, corner-stretch, rotate, save, puck on the new matrix.
