preserve separate UV Taylor denominator topologies

Keep the Taylor expansion's propagator powers instead of collecting different
terms over a common denominator. Remove the same collection before integrated
UV reduction and after final residue assembly. Existing term projection keeps
each numerator factorized with its original edge ownership.

Update the DOD1 topology regressions and exercise the actual Taylor pipeline
for the quartic GL24 case, checking exact equality, natural topologies and
owner-local ranks. Preserve the numerical route assertions and physics settings.

Ok, then proceed with full implementation and testing (starting from GL16 to make sure it terminates too). Implement this correction in general in core gammaloop production. Also make sure there is no similar forcing of common denominator anywhere else.
