fix(ci): increase Go test timeouts for cold runner performance

Cold runners with -race flag need 13-25 minutes for the full ./... suite
(compilation + race-instrumented execution), exceeding the previous:
- 60s diagnostic per-package timeout  -> 300s (handlers, pendinguploads)
- 10m main suite timeout             -> 30m
- 15m job-level ceiling               -> 35m

The OOM issue (mc#1099) was fixed by the 10m timeout, but that was
calibrated for warm cache (~5-7m). Cold runners hit 13-25m, causing
the suite to be killed mid-execution with non-zero exit, blocking all
staging PRs.

All 36 Go packages pass locally (non-race, ~20s total). No test changes
— only CI timeout calibration.
