mesh-delivery-gate and gitea: a setting check-gates-merge; false asks a reviewed pull request's Approve and merges it without waiting for mesh/check

The operator, 2026-10-25 22:56: "run the check locally only, but not as a gate, it loses us too much time". Tonight each
merge ask waited 3-7 minutes for mesh/check, and every merge into main refused the next approved merge for a check judged
on the trunk before (mesh-delivery#52). Both settings default to true, so nothing changes until the operator sets them.
False: the gate makes a reviewed pull request ready and asks its Approve with no verdict, a trunk's move puts nothing out
of date, a verdict is kept and shown, and a group still merges in one pass; the merge tool merges a head the Approve
names whatever its mesh/check says. delivery_status and show say the mode.
