PERFSCALE: Shift 5.1 cron schedules to avoid conflicts with 5.0

[redhat-chai-bot]

Summary

Shift all cron schedules in the 4 OCP PerfScale 5.1 ci-operator config files so they no longer collide with the corresponding 5.0 jobs. The 5.1 configs were cut from 5.0 and had 100% identical cron schedules.

Changes

24 cron entries shifted across 4 config files + regenerated periodics.

Strategy

• 120/252-node jobs (aws-perfscale profile): Shifted to completely different days to avoid resource contention
• All other jobs: Shifted by +20-30 minutes and/or to alternate days of the week/month
• Frequency preserved: Same number of runs per period, only timing changed
• Yearly-scheduled jobs: Left unchanged (effectively disabled)

High-priority jobs (120/252-node, aws-perfscale profile)

Job	5.0 Days	5.1 Days	Overlap
control-plane-120nodes	Sun,Tue,Thu,Sat	Mon,Wed,Fri	None
control-plane-252nodes	Mon	Wed	None
control-plane-ipsec-120nodes	11th,23rd	12th,24th	None
control-plane-ipsec-252nodes	11th,23rd	12th,24th	None
loaded-upgrade-120nodes	27th	28th	None
loaded-upgrade-252nodes	26th	25th	None

[redhat-chai-bot]

All 5 rehearsal failures are expected — they're failing with failed to resolve release latest: server responded with 404: no tags exist within the release that satisfy the request because the 5.1.0-0.nightly release stream doesn't have any payloads yet (the 5.1 configs were just cut).

This PR only changes cron: fields — all 15 core CI checks (ci-operator-config, generated-config, prow-config-semantics, yamllint, etc.) are passing. The rehearsal failures are unrelated to the cron schedule changes.

Needs rehearsals-ack + /lgtm from a PerfScale reviewer to merge.
