Merge remote-tracking branch 'origin/ci-adjustments' into integration_2026_w17 (!4059)

CI: Various CI adjustments

- RAN-SA-FHI72-CN5G: activate/inactive carriers on VVDN RU - to check if
  it improves reliability and stability of the pipeline
- RAN-SA-FHI72-CN5G: update CN with new IP range - avoid IP address
  overlap with CN used in RAN-SA-AERIAL-XXX pipelines
- RAN-SA-B200-Module-SABOX-Container: test with deltaMCS in SC-FDMA test
  case
- RAN-NSA-B200-Module-LTEBOX-Container: adjust PRACH DTX threshold to
  reduce number of false RA attempts on eNB
- remove retx check in RAN-SA-Multi-Antenna-CN5G and RAN-SA-AERIAL-CN5G -
  to avoid false CI failure caused by unsuccessful retx check of
  interfering UE
- adjust RAN-SA-Multi-Antenna-CN5G and RAN-SA-AERIAL-CN5G configs to
  improve UL throughput
