fix: report unmatched RayJob deletion rules

[cananoo]

Why are these changes needed?

When a terminal RayJob status matches no configured deletion rule, the controller currently logs the same success message as a fully processed rule set and takes no cleanup action. This can leave the RayCluster and RayJob resources behind without a visible signal, for example when activeDeadlineSeconds sets jobDeploymentStatus=Failed while jobStatus remains RUNNING.

This change:

• tracks whether any deletion rule matched;
• emits a Warning event with the terminal statuses when none matched;
• writes a distinct log message for the no-match case; and
• updates the deletion-rules sample to use jobDeploymentStatus: Failed for failure cleanup, covering infrastructure failures as well as application failures.

Deletion behavior is unchanged for matching rules.

Sample YAML misplaces ttlSeconds field

Medium Severity

On the Failed deletion rules, ttlSeconds is a sibling of condition rather than nested inside it. DeletionRule has no ttlSeconds field, so the API server drops those values and condition.ttlSeconds defaults to 0. Failed jobs then skip the documented 30/60/90-second staged cleanup and immediately run the most impactful overdue rule, DeleteSelf.

Fixed in follow-up commit d5fbb7b: the Failed deletion-rule ttlSeconds values are now nested under condition, so the staged 30/60/90-second cleanup behavior in the sample is preserved.
