fix(functions): gcf_gen1 fractional CPU to fit the Cloud Run CPU quota

Deploys kept failing container healthchecks with "Quota exceeded for total allowable CPU
per project per region" even in small batches: v2 gives every instance a full vCPU (needed
for concurrency 80), and ~35 services at 1 vCPU exceeds this new project's default Cloud Run
CPU quota under any accounting. cpu:'gcf_gen1' restores the gen1 fractional tiers
(256MiB → 1/6 vCPU) — a 6x smaller footprint, identical to how these functions ran on gen1.
Concurrency must be 1 with cpu<1; costless at dev scale. At launch: raise the quota, drop
these two options to restore full-vCPU concurrency.
