test(handlers): add coverage for runtime_provision_timeouts.go + classifyScheduleStatus edge cases

Add 20 new tests to admin_schedules_health_test.go:
- classifyScheduleStatus: zero threshold, negative threshold, exactly-at-threshold
  (strict > comparison boundary)
- loadRuntimeProvisionTimeouts: empty dir, non-dir entries, single/multiple
  templates, same-runtime MAX logic, zero/negative/missing runtime, bad YAML,
  missing config — all via t.TempDir() fixtures
