Extends DenseBlockedRouteParity (test-only, on 1573942) with the residual
dense-supported combinations named before any dense-route deletion:
- test_mrt_bodies: MRT on a periodic root with a passive circle, an
actuated circle (+/-) and a velocity Jet with an amplitude switch
(MRT slot/reservoir is rejected on every route: on_site_velocity is
SRT-only);
- test_two_bodies: two circles on a wider patch (4, 4, 28, 20), periodic
and slot/reservoir, Jet on one + passive other, and two actuated (+/-);
routes D/D, D/B [None, (8, 8)], B/B [(12, 8), (8, 8)].
Same gate: exact FP32 bits and NaN masks at 0, 1, 2, 8 and after
re-initialize; D/B vs B/B raw-exchange ledgers equal for every body.
Docstring table updated; no tolerance, no src change.
