Add per-machine probability override (#267)

* Add per-machine probability override

Flag to override an individual machine's pick probability by name.
Needed for an autojoined machine stuck at probability: 1: its
registration comes from per-org Datastore metadata (not siteinfo),
config is per-org not per-machine, and we can't disable the whole org.

* Bump build images to golang:1.26

go.mod requires go >= 1.26.2 (since #263) but the Docker and Cloud Build
images still pinned golang:1.25, so builds failed with GOTOOLCHAIN=local
refusing to build a module requiring a newer toolchain.

* Wire PROBABILITY_OVERRIDE env var into app.yaml

Declare PROBABILITY_OVERRIDE in both app.yaml templates and substitute
it from the _PROBABILITY_OVERRIDE Cloud Build variable, so the
-probability-override flag can be set on deployed App Engine services
via flagx.ArgsFromEnv.

* Bump m-lab/go to v0.1.77

v0.1.77 makes flagx.KeyValue ignore empty pairs (m-lab/go#205), so an
empty or unset PROBABILITY_OVERRIDE is a no-op instead of crashing the
service at startup. Removes the need for placeholder values on triggers
that don't set a probability override.
