Eva SarafianouandClaude Opus 4.7 b7a97f4bdc ci: disable fullyparallel for unsharded weekly Postgres jobs (#36390)
Restore the `fullyparallel: false` override for the unsharded
`Postgres with binary parameters` and `Postgres FIPS` jobs in the
weekly workflow. The override was originally added to the binary
parameters job in #35995 to prevent resource exhaustion on a single
runner, but was dropped when both jobs moved into
server-ci-weekly.yml in #36036, leaving them on the template default
of `true`.

Without it, the hosted runner is overwhelmed (too many server
instances, WebSocket hubs, and DB connections) and the runner agent
itself loses communication with GitHub mid-run, surfacing as
"hosted runner lost communication with the server" at ~55-60 min
into the Run Tests step. Both runs on April 27 and May 4 failed
this way; the sharded FIPS variant retained for FIPS-touching PRs
in server-ci.yml is unaffected because each shard handles only a
fraction of the packages.
