Commit Message

test: cover the rolling update partition helpers (#1041)

rollingUpdatePartition decides which replicas a rolling update is
allowed to touch next, and calculateContinuousReadyReplicas and
calculateLWSUnreadyReplicas feed it. A wrong partition either violates
maxUnavailable or leaves the rollout stuck. None of the three had a
direct test; they were only exercised through the integration suite.

Add table-driven cases for the behaviours the code encodes: the ready
tail is counted only while replicas are also updated; replicas without
a state yet count as unready; the partition advances by rollingStep from
the tail, is held while a replica below the window is not ready, still
drops for a not ready replica at the window edge so a broken rollout can
finish, and never moves back up.

Each case was checked by mutation: dropping the updated check, removing
the unavailable guard, letting the partition grow and ignoring missing
states each turn exactly the cases that guard them red.
