fix(pipeline): validate resolver ordinal buckets

[waveywaves]

Changes

• Validate the effective resolver leader-election bucket count against the rendered resolver StatefulSet replica count after additional options are applied.
• Preserve matching overrides and dynamic leader-election configurations.
• Reject out-of-range bucket overrides in StatefulSet ordinal mode.

The existing performance documentation already states that buckets must match replicas in ordinal mode.

Fixes #3957.
