krr: 1.7.1 -> 1.28.0

[JamieMagee]

Update krr and its dependency prometrix to fix the build. krr has been broken since mid-2024 because prometrix was marked broken against prometheus-api-client >= 0.5.3 (nixpkgs has 0.7.0). Upstream fixed the incompatibility a while ago.

• prometrix: 0.1.18-unstable-2024-04-30 -> 0.2.11-unstable-2026-03-11 (removes broken flag)
• krr: 1.7.1 -> 1.28.0

The upstream tests use a deprecated click API (CliRunner(mix_stderr=False)) so they're disabled. pythonImportsCheck passes and krr version returns 1.28.0.

Fixes: #327629
