fix(rollouts): surface an Inconclusive Experiment

An Inconclusive phase fell through to status-unknown and showed no banner,
so an Experiment whose analysis matched neither its success nor its failure
condition read as "no information" rather than as something needing a
decision. AnalysisRunRenderer already treats Inconclusive as a warning.

Inconclusive now maps to status-alert and gets a warning banner, matching
that renderer.
