v0.1.29 - Mix Editor % edits no longer rebalance other ingredients

Editing one ingredient's % now converts only that row to kg against the
Total mix anchor; other ingredients are left untouched (no proportional
redistribution). Removing a row likewise leaves the rest as-is. The hard
"percentages must total 100%" save guard is relaxed (kg is canonical and
the backend does not require 100%); the % chip remains as live feedback.
