Nikola JokicandCopilot App 8befb9d8d7 Derive the phase from an authoritative read of the child runners
patchAppliedActionableRevisionStatus reads the EphemeralRunnerSet through
the uncached reader precisely because a cached read cannot be trusted
there, then derived Status.Phase from a cached list of the child runners.
The optimistic lock on the patch covers the EphemeralRunnerSet object
alone, so it could not vouch for that list, while a successful write made
the result look consistent. The list also sits inside RetryOnConflict,
where a cached read can return the same stale data on every attempt.

The ownership filter moves into the process, because resourceOwnerKey is
a client-side index on the manager's cache and the API server rejects
.metadata.controller as an unsupported field label. The predicate lives
next to the indexer so the two do not drift apart.

Add the index to the revision patch test fakes, which need it now that
the function lists children, and a test that separates the two reads:
it fails when the list goes through the cache and passes when it does
not.
